The MAX8753 evaluation kit (EV kit) is a fully assembled

and tested surface-mount circuit board that generates

the voltages required for active-matrix, thin-film transis-

tor (TFT) liquid-crystal displays (LCDs). The EV kit con-

tains a pulse-width-modulated (PWM) step-up switch-

ing regulator (VMAIN), positive and negative charge-

pump regulators (OUTP and OUTN) for the TFT gate

drive, and a low-voltage linear regulator (OUTL).

The EV kit operates from a +2.6V to +5.5V (V

ply voltage. The step-up regulator switches at 1MHz and

is configured for a +9V output capable of providing

160mA with a +3V input. The positive and negative

charge pumps are configured for +24V and -11V, respec-

tively, and are both capable of providing 20mA. The lin-

ear voltage regulator (LDO) is configured to provide a

regulated +2.5V output with a maximum 300mA load.

The MAX8753 EV kit features low quiescent current and

high conversion efficiency (90%). Operation at 1MHz

allows the use of small surface-mount components. The

MAX8753 TQFN package (0.8mm max) with low-profile

external components allows the circuit to be less than

1.2mm high.
