AP3005 Overview
The AP3005 is a 420kHz fixed frequency PWM buck (step-down) DC-DC converter, capable of driving a 2A load with high efficiency, low ripple and excellent line and load regulation. The device includes a voltage reference, an oscillation circuit, an error amplifier, an internal PMOS and etc. The PWM control circuit is able to adjust the duty ratio linearly from 0 to 100%.
