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 (0.25Ω 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.

♦ Integrates All Active Circuitry for Three DC-DC

Converters

♦ Ultra-Small External Components

(ceramic capacitors, 2µH to 5µH inductors)

♦ DC-DC Converters Phase-Locked to Backplane

Frequency for Lowest Noise

High switching frequency (1MHz nominal) and phase-

loc ke d op e ra tion a llow the us e of s ma ll, minimum-

he ig ht e xte rna l c omp one nts while ma inta ining 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

a d jus te d to -20V with a d d itiona l c omp one nts . Als o

included are a logic-level shutdown and a “Ready” out-

put (RDY) that signals when all three outputs are in reg-

ulation.

♦ Low Operating Voltage (down to +2.8V)

♦ Adjustable Output Voltage from V to +5.5V

♦ Load Currents Up to 500mA

♦ Adjustable TFT Gate Driver Output:

Positive, V to +28V

Negative, 0 to -10V (-20V with added

components)

♦ Includes 0.35Ω Backplane Driver

♦ 1µA Shutdown Current

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 s up p lie d in a 1.1mm-hig h

TSSOP package.

♦ Power-Ready Output Signal
