MB39A119 DC/DC Converter IC

The MB39A119 is the Nch MOS drive of the synchronous rectification type DC/DC converter IC using pulse-width modulation (PWM) type that can charge Li-ion battery from 1 cell to 4 cells and suitable for down-conversion. This IC integrates built-in comparator for the voltage detection of the AC adapte.

MB39A119 Features

* High efficiency : 97 % (Max) High-frequency operation : 1 MHz (Max) Built-in off time control function Built-in voltage detection function of AC adapter (ACOK, XACOK terminal) Preventing mis-detection for the full charge by the constant voltage contr
