BCD Semiconductor Manufacturing Limited AP3406A
The AP3406A is a 1.1MHz fixed frequency, current mode, PWM synchronous buck (step-down) DC-DC converter, capable of driving a 800mA load with high efficiency, excellent line and load regulation. The device integrates a main switch and a synchronous switch without an external Schottky diode. It is ideal for powering portable equipment that runs from a single Li-ion battery.- Min Voltage : 2.5V
- Max Voltage : 5.5V
- Max Operating Temp : 85°C
- Min Operating Temp : -40°C
