Data Sheet

FN6367.1
5-Channel Integrated LCD Supply
The ISL97653A represents a fully integrated supply IC for
LCD-TV applications. With an input operating range of 4V to
14V, both commonly used LCD-TV input supplies, 5V and
12V, are supported. An A
VDD
supply up to 20V is generated
by a high-performance PWM BOOST converter with an
integrated 4.4A FET. V
ON
is generated using an integrated
charge pump with on-chip diodes and can be modulated using
an on-chip V
ON
slice control circuit. V
OFF
is generated using
an integrated charge pump controller. Additionally, the chip
allows for two logic supplies. A buck regulator with an
included 2.5A high side switch is used for the main logic
output and an internal LDO controller can be used to generate
a second logic LDO output.
To facilitate production test, an integrated HVS circuit is
included which can provide high voltage stress of the LCD
panel.
An on-board temperature sensor is also provided for system
thermal management control.
The ISL97653A is packaged in a 40 Ld 6mmx6mm QFN
package and is specified for operation over the -40擄C to
+105擄C temperature range.
