Description
The STOD32W is a triple DC-DC converter for AMOLED display panels. It integrates a step-up of 100 mA, inverting DC-DC converters and an auxiliary step-up converter. This device is particularly suitable for battery operated products, in which the major concern is the overall system efficiency. All three output voltages can be programmed by a dedicated pin, which implements SWIRE protocol.The auxiliary step-up positive output voltage is also configured by an external pull-down resistor. Soft-start with controlled inrush current limit, thermal shutdown and short-circuit protection are integrated functions of the device. Flip Chip 12 (1.618x1.710 mm)
