Description
The STOD02 is a dual DC-DC converter meant to
power AMOLED displays. It integrates a step up
and an inverting DC-DC converter making it
particularly suitable for battery operated products,
where the major concern is the overall system
efficiency. STOD02 works in pulse skipping mode
during low load condition and in PWM-mode (at
1.6 MHz) for medium/high load condition. The
high frequency allows reducing the value and
number of external components just to 6
components needed. The enable pin allows
turning off the device so reducing the current
consumption to less that 1 µA. The negative
output voltage can be programmed by an MCU
through a dedicated pin which implements singlewire protocol. Soft-start with controlled inrush
current limit and thermal shutdown are integrated
functions of the device.
