M62216FP Datasheet, PDF (1/8 Pages) Mitsubishi Electric Semiconductor – Low Voltage Operation STEP-UP DC-DC Converter

MITSUBISHI SEMICONDUCTOR<STD-Linear IC>
M62216FP/GP
Low Voltage Operation STEP-UP DC-DC Converter
DESCRIPTION
The M62216FP is designed as low voltage operation STEP-UP
DC-DC converter.
This IC can operate very low input voltage (over 0.9V) and low
power dissipation (circuit current is less than 850µA).
So, this IC suitable for power supply of portable system that
using low voltage battery (DRY battery, rechargeable battery).
