STOD32A 300 mA triple DC-DC converter for powering AMOLED displays Data brief Overtemperature protection True-shutdown mode Short-circuit protection Package QFN16 (3.0x3.0 mm), 0.5 mm pitch Applications Active matrix OLED power supply in portable QFN16(3.0x3.0 mm) devices Cellular phones, multimedia players, camcorders and digital still cameras Features Operating input voltage range from 2.5 V to Description 4.5 V The STOD32A is a triple DC-DC converter for 300 mA output current for step-up and AMOLED display panels. It integrates 300 mA inverting converters (VIN> 2.9 V) step-up and inverting DC-DC converters plus 55 mA output current for an auxiliary step-up auxiliary step-up converter. This device is converter (V > 2.9 V) IN particularly suitable for battery operated products, 4.6 V positive step-up converter in which the major concern is overall system Programmable negative voltage from - 0.8 V efficiency. Output voltages can be programmed to - 4.8 V default -4.0 V by a dedicated pin, which implements S WIRE Auxiliary step-up converter positive voltage protocol. Soft-start with controlled inrush current limit, thermal shutdown and short-circuit programmable step from 5.8 V to 7.9 V default 7.6 V protection are integrated functions of the device.
