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_WIRE protocol. Soft-start with
controlled inrush current limit, thermal shutdown
and short-circuit protection are integrated
functions of the device.
