Description
The STOD14 is a dual channel DC-DC converter driver for medium-sized AMOLED display panels. It integrates a step-down and an inverting converter in a compact IC design. The excellent efficiency makes it particularly suitable for battery operated products. The high frequency operation allows the value and size of external components to be reduced.
