A8603KESTR-J Datasheet PDF - Allegro MicroSystems

DESCRIPTION
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.
