Description
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.
