Overview
Alfa-MOS Technology AF1202A 300KHz, 2.
6A / 23V Step-Down Converter General Description AF1202A consists of step-down switching regulator with PWM control.
These devices include a reference voltage source, oscillation circuit, error amplifier, internal PMOS and etc.
AF1202A provides low-ripple power, high efficiency, and excellent transient characteristics.
The PWM control circuit is able to very the duty ratio linearly from 0 up to 100%.
This converter also contains an error amplifier circuit as well as a soft-start circuit that prevents overshoot at startup.
An enable function, an over current protect function and a short circuit protect function are built inside, and when OCP or SCP happ...
