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 resis-
tors. 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.
