A4406 Overview
The A4406 is an automotive power management IC that uses a high frequency constant on-time 5.45 V pre-regulator to supply an internal 5 V linear regulator and a 3.3 V linear DMOS driver. Designed to supply CAN and microprocessor power supplies in high temperature environments, the A4406 is ideal for under hood applications. Efficient operation is achieved by using a buck pre-regulator to efficiently drop the input...
