TEXAS INSTRUMENTS TL1454 TL1454Y handbook

The TL1454/TL1454Y are dual-channel pulse-width-modulation (PWM) control circuits, primarily intended for low-power dc/dc converters. Applications include LCD displays, backlight inverters, notebook computers and other products requiring small, high-frequency dc/dc converters. Each PWM channel has its own error amplifier, PWM comparator, dead-time control comparator, and MOSFET driver. The voltage reference, oscillator, undervoltage lockout and short-circuit protection are common to both channels. Channel 1 is configured to drive n-channel MOSFETs in step-up or flyback converters, and channel 2 is configured to drive p-channel MOSFETs in step-down or inverting converters. The operating frequency is set with an external resistor and an external capacitor, and dead time is continuously adjustable from 0 to 100% duty cycle with a resistive divider network. Soft start can be implemented by adding a capacitor to the dead-time control (DTC) network. The error-amplifier common-mode input range includes ground, therefore this circuit can be used in low-voltage applications.
