A8601: Multiple-Output Regulator for Automotive LCD Displays

The A8601 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, to minimize interference with AM and FM radio bands.

A total of five output voltages are provided, from three linear regulators and two charge-pump regulators. Each output voltage can be adjusted independently. During power-up and shutdown, the outputs are turned on and off in preprogrammed sequences, to 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. Input disconnect protection is achieved by driving an external P-MOSFET.

28-pin exposed thermal pad TSSOP package allows operation at high ambient temperatures. It is lead (Pb) free with 100% matte-tin leadframe plating.

Applications:

  • GPS
  • Infotainment
  • Medium LCDs
DATASHEETS
