STOD14 STOD14 700mA dual DC/DC converter for powering AMOLED display

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.

The positive output voltage is fixed at 4.6 V with very high current capability and is generated using a buck converter. The negative output is programmable by an external MCU through a dedicated pin which implements single-wire protocol, with values from - 2.4 to - 6.0 V.

Soft-start with controlled inrush current limit, load disconnect and thermal shutdown are integrated functions of the device
