Product Summary

The 39A126 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 39A126 integrates the build-in comparator for the voltage detection of the AC adapter, and selects the AC adapter or battery auto-matically for power supply to the system. Provides a wide range of power supply voltage, low standby current, and high efficiency, which makes the 39A126 ideal as a built-in charging device in products such as notebook PC.
