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.

Application(s)

  • LCD TV
  • Set Top Box
  • Portable DVD
  • Digital Photo Frame
