RN5RYxx1 SERIES
OUTLINE
NO. EA-030-130502
The RN5RYxx1 Series are CMOS-based VFM Control ICs for step-up DC/DC converter with an external dri-
ver transistor featuring high output voltage accuracy and low supply current. Each of the RN5RYxx1 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 RN5RYxx1 Series with only an
inductor, a diode, a capacitor, and a drive transistor.
is possible.
Since the package for these ICs is SOT-23-5( Mini-mold)package, high density mounting of the ICs on boards
