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
implements S_WIRE protocol.The auxiliary step-up
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.
