Voltage Mode PWM Controller 3A 8-Pin SOP T/R

The AP2014 controller IC is designed to provide a low cost synchronous Buck regulator for on-board DC to DC converter applications. With today’s ASIC products requiring supply voltages at 1.8V and lower, when the output current is as much as 3A and the input voltage is at either 3.3V or 5V, traditional linear regulator simply incurs too much loss within itself. The AP2014 together with dual N-channel MOSFETs provide a low cost solution for such applications. This device features an internal 200KHz oscillator (400KHz for "A" version), under-voltage lockout for both Vcc and Vc supplies, an external programmable soft-start function as well as output under-voltage detection that latches off the device when an output short is detected.
