Description

The STOD32A is a triple DC-DC converter for

AMOLED display panels. It integrates 300 mA

step-up and inverting DC-DC converters plus

auxiliary step-up converter. This device is

particularly suitable for battery-operated

products, in which the major concern is overall

system efficiency. Output voltages can be

programmed by a dedicated pin, which

implements S_WIREprotocol. Soft-start with

controlled inrush current limit, thermal shutdown

and short-circuit protection are integrated

functions of the device.

300 mA output current for step-up and

inverting converters (V_IN> 2.9 V)

55 mA output current for an auxiliary step-up

converter (V_IN> 2.9 V)

4.6 V positive step-up converter

Programmable negative voltage from - 0.8 V

to - 4.8 V default -4.0 V

Auxiliary step-up converter positive voltage

programmable step from 5.8 V to 7.9 V

default 7.6 V



Soft-start with inrush current protection
