________________General Desc ription
The MAX1664 integrates power-supply and backplane
drive circuitry for active-matrix thin-film-transistor (TFT) liq-
uid crystal displays. Included are a single-output, pulse-
width-modulation boost converter (0.25
switch), a
dual-output (positive and negative) gate-driver supply
using one inductor, an LCD backplane driver, and a sim-
ple phase-locked loop to synchronize all three outputs.
High switching frequency (1MHz nominal) and phase-
locked operation allow the use of small, minimum-
height external components while maintaining low
output noise. A +2.8V to +5.5V input voltage range
allows operation with any logic supply. Output voltages
are adjustable to +5.5V (DC-DC 1) and to +28V and
-10V (DC-DC 2). The negative output voltage can be
adjusted to -20V with additional components. Also
included are a logic-level shutdown and a “Ready” out-
put (RDY) that signals when all three outputs are in reg-
ulation.
The boost-converter operating frequency can be set at
16, 24, or 32 times the backplane clock. This flexibility
allows a high DC-DC converter frequency to be used
with LCD backplane clock rates ranging from 20kHz to
72kHz. The MAX1664 is supplied in a 1.1mm-high
TSSOP package.
