Description

The STOD32W is a triple DC-DC converter for

AMOLED display panels. It integrates a step-up of

100 mA, inverting DC-DC converters and an

auxiliary step-up converter. This device is

particularly suitable for battery operated products,

in which the major concern is the overall system

efficiency. All three output voltages can be

programmed by a dedicated pin, which

positive output voltage is also configured by an

external pull-down resistor. Soft-start with

controlled inrush current limit, thermal shutdown

and short-circuit protection are integrated

functions of the device.
