Overview
Data Sheet 340kHz, 3A Synchronous DC-DC Buck Converter AP3503 General Description The AP3503 is a 340kHz fixed frequency, current mode, PWM synchronous buck (step-down) DC-DC converter, capable of driving a 3A load with high efficiency, excellent line and load regulation.
The device integrates N-channel power MOSFET switches with low on-resistance.
Current mode control provides fast transient response and cycle-by-cycle current limit.
The AP3503 employs complete protection to ensure system security.
Including output Over Voltage Protection, input Under Voltage LockOut, programmable soft-start, Over Temperature Protection to safeguard the circuit.
This IC is available in PSOP-8 package.
