RICOH RN5RY202 handbook

The RN5RY202 is a VFM (chopper) control IC that is a high output voltage accuracy, low supply current CMOS process step-up DC/DC converter control IC. The RN5RY202 consists of a voltage reference unit, an error amplifier, an oscillator, a VFM control circuit and feedback resistors. The output voltage is fixed at 2V in the IC. A low ripple, high efficiency step-up DC/DC converter can be constructed by simply adding an inductor, a diode, a capacitor, and a drive transistor and feedback resistors. Although the series have no CE pins unlike RN5RY××1A, high voltage (VOUT=30V) can be also output by using external feedback resistors.
