AP3502F

Data Sheet 340kHz, 2A Synchronous DC-DC Buck Converter AP3502F General Description The AP3502F 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 AP3502F 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: 4.5V to 18V Fixed 340kHz Frequency High Efficiency: up to 95% Output Current: 2A Current Mode Control Built-in Over Current Protection Built-in Thermal Shutdown Function Built-in UVLO Function Built-in Over Voltage Protection Programmable Soft-start...
