Rev 3.00
March 7, 2012 5 Channel DC/DC Converter + VON Slice + Power Good Features 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. 9.5V to 15.0V Input Supply 1.3MHz Switching Frequency 5.5A Integrated Boost for Up to 19V AVDD VON Charge Pump, Up to 36V and 120mA 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. VOFF Charge Pump, Down to -10V and 120mA Synchronous Buck1 for 3.3V/2.5V with 2.0A Peak FET Synchronous Buck2 Controller Output from 0.9V to 2.0V 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. On-board AVDD Delay Switch VON Slice Function Integrated Power Good Function for TCON Enable The second logic voltage is generated from a synchronous buck
converter with MOSFET controllers. The overcurrent protection is
also integrated with the buck. Automatic Start-Up Sequencing 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. Specified for Ambient Operation Over the -40В°C to +85В°C
Temperature Range UVLO, UVP, OVP, OCP, and OTP Protection 40 Ld 6x6 QFN Pb-Free (RoHS Compliant) Applications Alternative fixed voltages at the boost, Buck1, Buck2, VON charge
pump, and VOFF charge pump are available in ISL98602. LCD TV Pin Configuration FN7699 Rev 3.00
