Data Sheet 340kHz, 2A Synchronous DC-DC Buck Converter AP3502 General Description The AP3502 is a 340kHz 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 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 AP3502 employs complete protection to ensure system security, including output Over Voltage Protection, input Under Voltage LockOut, programmable soft-start, and Over Temperature Protection. This IC is available in SOIC-8 package. Features • Input Voltage Range: 4.
