STOD02 Dual DC-DC converter for powering AMOLED display

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.
