ISL97652

4-Channel Integrated LCD Supply with

The ISL97652 represents a high power, integrated LCD

supply IC targeted at large panel LCD displays. The

output. Feedback is taken from the far side of the delay FET

for improved regulation and an OVP circuit protects output

side components. The boost features programmable

soft-start.

The asynchronous buck converter features an integrated

2.5A FET. It also operates from the 650kHz or 1.3MHz

internal clock and features separate enable and soft-start

control.

the use of small output components for board space

The integrated amplifiers feature high slew-rate and high

output current capability. They are permanently enabled

when AVIN is present.

Available in the 48 Ld 7mmx7mm QFN package, the

ISL97652 is specified for ambient operation over the

-40°C to +85°C temperature range.
