The MAX5060/MAX5061 pulse-width modulation (PWM) DC-DC controllers provide high-output-current capability in a compact package with a minimum number of external components. These devices utilize an average-current-mode control that enables optimal use of low RDS(ON) MOSFETs, eliminating the need for external heatsinks even when delivering high output currents. Differential sensing (MAX5060) enables accurate control of the output voltage, while adaptive voltage positioning provides optimum transient response. An internal regulator enables operation with 4.75V to 5.5V or 7V to 28V input voltage ranges. The high switching frequency, up to 1.5MHz, allows the use of low-output inductor values and input capacitor values. This accommodates the use of PC-board-embedded planar magnetics. The MAX5060 features a clock output with 180° phase delay to control a second out-of-phase converter for lower capacitor ripple currents. The MAX5060 also limits the reverse current if the bus voltage becomes higher than the regulated output voltage. The MAX5060 is specifically designed to limit current sinking when multiple power-supply modules are paralleled. The MAX5060/MAX5061 offer an adjustable 0.6V to 5.5V output voltage. The MAX5060 offers an overvoltage protection, power-good signal, and an output enable function. The MAX5060/MAX5061 operate over the automotive temperature range (-40°C to +125°C). The MAX5060 is available in a 28-pin TSOT23-6 package.

The MAX5058/MAX5059 enable secondary-side synchronous rectification in isolated power supplies using widely available power MOSFETs. These devices facilitate the commutation of the secondary-side MOSFETs by providing a clean gate-drive signal that is synchronized to the power MOSFET switching in the primary side of the isolation transformer. The MAX5058/MAX5059 complement the MAX5051 and MAX5042/MAX5043 primary-side PWM ICs and enable the design of high-efficiency synchronously rectified isolated power supplies. Simultaneous conduction of the primary side and the freewheeling synchronous rectifier MOSFET is avoided by having a look-ahead signal (before the primary-side MOSFETs turn ON), thus eliminating large current spikes resulting from a shorted transformer secondary. An on-board error amplifier with a versatile current reference output enables virtually unlimited possibilities in reference-voltage generation. Reference voltage for the error amplifier is generated by connecting an appropriate resistor to this output. Low on-resistance margining MOSFETs integrated on-chip allow for implementation of a margining circuit without the use of external switches. The MAX5058 provides a 5V LDO output for logic-level MOSFETs while the MAX5059 provides a 10V LDO output for conventional 10V MOSFETs. The MAX5058/MAX5059 are designed to enable paral- leling of multiple power supplies for accurate current sharing using a sim

The MAX504/MAX515 are low-power, voltage-output, 10-bit digital-to-analog converters (DACs) specified for single +5V power-supply operation. The MAX504 can also be operated with ±5V supplies. The MAX515 draws only 140µA, and the MAX504 (with internal reference) draws only 260µA. The MAX515 comes in 8-pin DIP and SO packages, while the MAX504 comes in 14- pin DIP and SO packages. Both parts have been trimmed for offset voltage, gain, and linearity, so no fur- ther adjustment is necessary. The MAX515’s buffer is fixed at a gain of 2. The MAX504’s internal op amp may be configured for a gain of 1 or 2, as well as for unipolar or bipolar output voltages. The MAX504 can also be used as a four-quadrant multiplier without external resistors or op amps. For parallel data inputs, see the MAX503 data sheet. For a hardware and software compatible 12-bit upgrade, refer to the MAX531/MAX538/MAX539 data sheet.

The MAX5042/MAX5043 are isolated multimode PWM power ICs that feature integrated switching power MOSFETs connected in a voltage-clamped, two-transistor, power-circuit configuration. These devices operate from a wide 20V to 76V input voltage range. The MAX5042 includes a hot-swap controller for use with an external power MOSFET to limit inrush current for applications where the power supply is plugged into a live power backplane. The MAX5043 does not include a hot-swap controller. The voltage-clamped power topology of the MAX5042/MAX5043 enables full recovery of stored magnetizing and leakage inductive energy for enhanced efficiency and reliability. Operating at up to 500kHz switching frequency, these devices provide up to 50W of output power. The MAX5042/MAX5043 allow the implementation of both forward and flyback voltage or current-mode converter topologies. A dedicated latched external shutdown provides protection in addition to internal thermal shutdown. The MAX5042/MAX5043 achieve higher efficiency when used with secondary-side synchronous rectification. These devices generate a look-ahead signal for driving secondary-side synchronous rectifiers. The MAX5042/MAX5043 are rated for operation over the -40°C to +125°C and -40°C to +85°C temperature range, respectively, and are available in a small surface-mount 56-pin thin QFN package.

The MAX503 is a low-power, 10-bit, voltage-output digital-to-analog converter (DAC) that uses single 5V or dual ±5V supplies. This device has an internal voltage reference plus an output buffer amplifier. Operating current is only 250µA from a single 5V supply, making it ideal for portable and battery-powered applications. In addition, the shrink small-outline package (SSOP) measures only 0.1 square inches, using less board area than an 8-pin DIP. 10-bit resolution is achieved through laser trimming of the DAC, op amp, and reference. No further adjustments are necessary. Internal gain-setting resistors can be used to define a DAC output voltage range of 0V to +2.048V, 0V to +4.096V, or ±2.048V. Four-quadrant multiplication is possible without the use of external resistors or op amps. The parallel logic inputs are double buffered and are compatible with 4-bit, 8-bit, and 16-bit microprocessors. For a hardware and software compatible 12-bit upgrade, refer to the MAX530 data sheet. For DACs with similar features but with a serial data interface, refer to the MAX504/MAX515 data sheet.

The MAX5038A/MAX5041A dual-phase, PWM controllers provide high-output-current capability in a compact package with a minimum number of external components. The MAX5038A/MAX5041A utilize a dual-phase, average-current-mode control that enables optimal use of low RDS(ON) MOSFETs, eliminating the need for external heatsinks even when delivering high output currents. Differential sensing enables accurate control of the output voltage, while adaptive voltage positioning provides optimum transient response. An internal regulator enables operation with input voltage ranges of +4.75V to +5.5V or +8V to +28V. The high switching frequency, up to 500kHz per phase, and dual-phase operation allow the use of low-output inductor values and input capacitor values. This accommodates the use of PC board-embedded planar magnetics achieving superior reliability, current sharing, thermal management, compact size, and low system cost. The MAX5038A/MAX5041A also feature a clock input (CLKIN) for synchronization to an external clock, and a clock output (CLKOUT) with programmable phase delay (relative to CLKIN) for paralleling multiple phases. The MAX5038A/MAX5041A also limit the reverse current in case the bus voltage becomes higher than the regulated output voltage. The MAX5038A offers a variety of factory-trimmed preset output voltages (see Selector Guide) and the MAX5041A offers an adjustable output voltage between +1.0V to +3.3V.

The MAX5025-MAX5028 are constant-frequency, pulse-width modulating (PWM), low-noise boost converters designed for low-voltage systems that require locally generated high voltage. They are capable of generating low-noise, high output voltages required for varactor diode biasing in TV tuners, set-top boxes, and PCI cable modems. The MAX5025-MAX5028 operate from as low as 3V and switch at 500kHz. The constant-frequency, current-mode PWM architecture provides for low output noise that is easy to filter. A 40V lateral DMOS device is used as the internal power switch, making the devices ideal for boost converters up to 36V. The MAX5025/MAX5026 adjustable versions require the use of external feedback resistors to set the output voltage. The MAX5027/MAX5028 offer a fixed 30V output.
