Multiple Output Reg. For Auto Lcd Displays A8603KESTR-R
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. An I2C-compliant serial interface allows a system microcontroller to configure the A8603 by writing into its internal registers. A system controller can also access A8603’s status registers in case of fault conditions. The A8603 incorporates a boost stage followed by two linear regulators and two charge-pump regulators. Each output voltage can be programmed independently through serial interface. During power-up and shutdown, the outputs are turned on and off in preprogrammed sequences with adjustable delay. This will meet the sequencing requirements for specific LCD panels. Short-circuit protection is provided for all outputs. The boost switch is protected against overcurrent and overvoltage. The A8603 comes in a 24-pin 4 × 4 mm QFN package, with exposed thermal pad to allow operation at high ambient temperatures. It is lead (Pb) free with 100% matte-tin leadframe plating.
