Description

AX4102 consists of step-down switching regulator with PWM control. These devise
include a reference voltage source, oscillation circuit, error amplifier, internal PMOS and
etc.

The device provides low-ripple power, high efficiency, and excellent transient
characteristics. The PWM control circuit is able to the duty ratio linearly form 0 up to 100%. An enable function, an over current protect function and short circuit protect function are built inside, and when OCP or SCP happens, the operation frequency will be reduced. Also, an internal compensation block is built in to minimum external component count.

Features 

1. Input voltage：3.6V to 23V
