A8603 Datasheet Multiple-output Regulator

Manufacturer: Allegro MicroSystems

Overview: A8603 Multiple-Output Regulator for Automotive LCD Displays.

This datasheet includes multiple variants, all published together in a single manufacturer document.

Datasheet Details

The A8603 is a fixed-frequency, multiple-output supply for LCD bias.

Its switching frequency can be either programmed or synchronized with an external clock signal between 350 kHz and 2.25 MHz.

This will minimize interference with AM and FM radio bands.

Automotive-grade AEC-Q100 qualified.
Input voltage from 3 to 10 V.
Four individual output supplies.
Independent control of each output voltage.
Boost switching frequency: 350 kHz to 2.25 MHz.
External synchronization capability is available.
Frequency dithering to reduce EMI.
Less than 10 μA shutdown current.
Protection features: overcurrent, overvoltage, short circuit, and thermal overload protection.
Ful.
