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 SWIRE protocol. 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 (VIN > 2.9 V)
55 mA output current for an auxiliary step-up
converter (VIN > 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
