OUTLINE

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.
