4-Channel Integrated LCD Supply with
Dual V COM Amplifiers
The ISL97652 represents a high power, integrated LCD
supply IC targeted at large panel LCD displays. The
ISL97652 integrates a high power, boost converter for A VDD
generation, delay switch, regulated V ON and V OFF charge
pumps, V ON slicing circuitry, a buck regulator for logic supply
generation and dual high power V COM amplifiers.
Operating at 650kHz or 1.3MHz, the A VDD boost converter
features a 2.8A boost FET. A short circuit protected A VDD
delay switch is integrated to provide sequencing of the A VDD
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 dual charge pump controllers used for V ON and V OFF
generation uses the full F OSC switching frequency to allow
the use of small output components for board space
efficiency. V ON is further processed through an integrated
V ON-SLICE circuit for reduced flicker.
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.
