MITSUBISHI SEMICONDUCTOR 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).
