RN5RY201A General Description

The RN5RY´´1 Series are VFM Control ICs for step-up DC/DC converter with an external driver transistor featuring high output voltage accuracy and low supply current by CMOS process. Each of the RN5RY´´1 Series ICs consists of a voltage reference unit, an error amplifier, an oscillator, a VFM control circuit and feed back resistors. A low ripple, high efficiency step-up DC/DC converter can be composed of the RN5RY´´1 Series with only an inductor, a diode, a capacitor, and a drive transistor.

Since the package for these ICs are SOT-23-5( Mini-mold)package, high density mounting of the ICs on boards is possible.
