Fujitsu MB39A126 39A126 dc/dc converter for charging ic
Brand New & Original Packing Fujitsu IC Chipsets
Brand: Fujitsu Microelectronics FUJITSU
(DC/DC Converter for charging(3/4-cells)
Pin Package: 24pin SSOP
MB39A126 (DC/DC Converter for charging(3/4-cells) 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 comparator 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 in products such as notebook PC.
Built-in two constant current control circuits
Analog control of the charging current value (+INE1, +INE2 terminal)
Built-in AC adapter voltage detection function (ACOK, XACOK terminal)
