General Description

The A4410 is power management IC that uses a buck or buck/ boost pre-regulator to efficiently convert automotive battery voltages into a tightly regulated intermediate voltage complete with control, diagnostics, and protections.

The output of the pre-regulator supplies a 5 V/250 mAMAX tracking/protected LDO, a 3.3 V/160 mAMAX LDO, a 5 V/150 mAMAX LDO, and a 1.25 V/750 mADC/1 APEAK synchronous buck regulator.

Designed to supply CAN or microprocessor power supplies in high temperature environments the A4410 is ideal for under hood applications.

Overview

A4410 Adjustable Frequency Buck or Buck/Boost Pre-Regulator with a Synchronous Buck, 3 Internal LDOs, Window Watchdog Timer, and.
