... PDAs ■ Camcorders and digital still cameras 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 ...
