DC/DC Converter IC for Charging Li-ion Battery
MB39A125/126
- DESCRIPTION
MB39A125/126 is a DC/DC converter IC for charging Li-ion battery, which is suitable for down-conversion, and uses pulse width modulation (PWM) for controlling the output voltage and current independently. This IC integrates the build-in parator for the voltage detection of the AC adapter, and selects the AC adapter or battery automatically for power supply to the system. Provides a wide range of power supply voltage, low standby current, and high efficiency, which makes them ideal as a built-in charging device...
