VFM STEP-UP DC/DC CONVERTER CONTROLLER
| The RN5RYxx1 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. The RN5RYxx1
Series ICs consist 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 constructed of the RN5RYxx1
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. |
