AP3512E
AP3512E is 2A Synchronous DC-DC Buck Converter manufactured by BCD.
Preliminary Datasheet
18V, 2A Synchronous DC-DC Buck Converter
General Description
The AP3512E is a 500k Hz 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 plete protection to ensure system security, including output Over Voltage Protection, input Under Voltage Lock Out, programmable Soft-start, Over Temperature Protection and hiccup mode Short Circuit Protection.
This IC is available in SOIC-8 and PSOP-8 packages.
