TFT LCD DC-DC Converter with
Integrated Charge Pumps
General Description
The MAX8753 quadruple-output DC-DC converter pro-
vides the regulated voltages required by active-matrix,
thin-film transistor (TFT), liquid-crystal displays (LCDs).
It includes a high-power step-up regulator (V MAIN ), two
low-power charge pumps (V POS and V NEG ), and a low-
voltage 300mA linear regulator (V LOGIC ).
The step-up DC-DC converter is a high-frequency
(1MHz) current-mode regulator with a built-in power
MOSFET that allows the use of ultra-small inductors and
ceramic capacitors. It provides fast transient response
to pulsed loads and includes an automatic pulse-skip-
ping mode that increases efficiency over a wide-load
current range. The 1.5A current limit allows a +10V out-
put at more than 300mA from a +3.3V input.
The two charge pumps independently regulate one
positive and one negative output voltage. The positive
charge pump is a voltage tripler that accepts an input
voltage up to +13V and delivers a 20mA output up to
+28V without external switches or diodes. The negative
charge pump inverts an input voltage up to +24V and
delivers a 20mA negative output using external diodes.

Ordering Information
The logic linear regulator converts the IC’s +2.6V-to-
+5.5V input to a regulated +2.5V or adjustable output.
