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.
Parametrics
39A126 absolute maximum ratings: (1)Power supply voltage, VCC: 28 V; (2)Output current, IOUT: 60 mA; (3)Peak output current, IOUT: 700 mA; (4)Power dissipation, PD: 740 mW; (5)Storage temperature, TSTG: -55 +125℃.
Features
39A126 features: (1)High efficiency: 97% (MAX); (2)Built-in two constant current control circuits; (3)Analog control of the charging current value (+INE1, +INE2 terminal); (4)Built-in AC adapter voltage detection function (ACOK, XACOK terminal).
