Description
The M62216FP is designed as low voltage operation STEP-UP DC/DC converter.
This IC can operate very low input voltage (over 0.9 V) and low power dissipation. (circuit current is less than 850 µA)
So, this IC suitable for power supply of portable system that using low voltage battery. (DRY battery, rechargeable
battery)
Features
• Pre-drive type PWM output (Pre-drive only)
• Low voltage operation: VIN = 0.9 V min.
• Low current dissipation: IB = 850 µA typ.
• Pre-drive output current can be adjusted
• Built-in ON/OFF Function: IB (OFF) = 35 µA typ.
• Application for STEP-DOWN Converter can be used
Application
DC/DC Converter for portable sets of battery used
