Description
The ISL98602 represents a high-power, integrated LCD supply IC targeted at large panel LCD displays. The ISL98602
integrates a high-power boost converter for AVDD generation, VON and VOFF charge pump drivers, one synchronous
buck regulator, and one synchronous buck controller for two logic voltages. The VON slicing circuitry and power good
function are also included.

Operating at 1.3MHz, the AVDD boost converter features a 5.5A boost FET. Feedback is taken from the far side of the
delay FET for improving regulation. The OVP circuit protects output side components.
The logic synchronous buck converter features two 2.3A FETs operating at 1.3MHz internal clock. The output voltage is
set by the IC internally or with a feedback resistor. The soft-start circuitry is also integrated with the buck.
The second logic voltage is generated from a synchronous buck converter with MOSFET controllers. The overcurrent
protection is also integrated with the buck.
The charge pump of VON and VOFF uses the full switching frequency and integrates the driver for high current capability.
VON is further processed through an integrated VON slice circuit in order to reduce flicker.
Alternative fixed voltages at the boost, Buck1, Buck2, VON charge pump, and VOFF charge pump are available in
ISL98602; please contact Intersil Marketing via e-mail at rmonteir@intersil.com.
