AP3403 Overview
The AP3403 is a 2.0MHz fixed frequency, current mode, PWM synchronous buck (step-down) DC-DC converter, capable of driving a 600mA load with high efficiency, excellent line and load regulation. The high efficiency is easily configured by using an inductor, resistors and capacitors as the external ponents. Current mode control provides fast transient response and cycle-by-cycle current limit.
