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.
