AX3131
PWM Control 3A Step-Down Converter
GENERAL DESCRIPTION AX3131 consists of step-down switching
regulator with PWM control.
These devise include a reference voltage source, oscillation circuit, error amplifier, internal PMOS and etc.
AX3131 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%.
The converter frequency can be set by outside resistance.
The wide range is from 200K to 1.
3MHz.
AX3131 is build out soft start function that prevent inrush current and overshooting.
A shutdown switch, over current protect and short circuit protect functions are built inside, and when SC...
