Description

The STOD03AS is a dual DC-DC converter with

short-circuit protection for AMOLED display

panels. It integrates a step-up and an inverting

DC-DC converter making it particularly suitable

for battery operated products, in which the major

concern is overall system efficiency. It works in

pulse skipping mode during light load conditions

and PWM-MODE at 1.5 MHz frequency for

medium/high load conditions. The high frequency

allows the value and size of external components

to be reduced. The Enable pin allows the device

to be turned off, therefore reducing the current

consumption to less than 1 µA. The negative

output voltage can be programmed by an MCU

through a dedicated pin which implements single-

wire protocol. Soft-start with controlled inrush

current limit and thermal shutdown are integrated

functions of the device.
