Description

The STOD13AM is a dual DC-DC converter 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

low 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, thermal

shutdown, and short-circuit protection are

integrated functions of the device.
