Description:

Valley current mode control buck converter

A4403 Features

* ▪ Extremely fast load-transient response with minimal output voltage delta ▪ Achieves high step-down ratios with on-times < 50 ns ▪ User-configurable on-time, achieving switching frequencies up to 2 MHz ▪ Minimal external components required ▪ Optimized for low value filter capacitors and inductors

A4403 General Description

The A4403 is a buck converter that uses valley current-mode control. This control scheme allows very short switch on-times to be achieved, making it ideal for applications that require high switching frequencies combined with high input voltages and low output voltages. Low cost is accomplished thro.
