Preliminary Datasheet
18V, 2A Synchronous DC-DC Buck Converter
AP3512E
General Description
The AP3512E is a 500kHz fixed frequency, current mode, PWM synchronous buck (step-down) DC-DC converter, capable of driving a 2A load with high efficiency, excellent line and load regulation.
The AP3512E exhibits high efficiency at light load.
The device integrates N-channel power
MOSFET switch with low on-resistance.
Current mode control provides fast transient response and cycle-by-cycle current limit.
The AP3512E employs complete protection to ensure system security, including output Over
Voltage Protection, input Under
Voltage Lock Out, programmable Soft-start, Over Temperature Protection and hi...
