STOD32W 100 mA triple DC-DC converter for powering AMOLED displays Data brief True-shutdown mode Short-circuit protection Package Flip Chip 12 bumps (1.618 x 1.710 mm), 0.4 mm pitch Applications Active matrix OLED power supply in portable devices Flip Chip 12 (1.618 x 1.710 mm) Cellular phones, multimedia players, camcorders and digital still cameras Features Operating input voltage range from 2.9 V to Description 4.5 V The STOD32W is a triple DC-DC converter for 100 mA output current for step-up and AMOLED display panels. It integrates 100 mA inverting converters (V > 2.9 V) IN 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) particularly suitable for battery operated products, IN 4.6 V positive step-up converter in which the major concern is overall system efficiency. Output voltages can be programmed Programmable negative voltage from - 0.8 V to - 4.6 V default -3.0 V by a dedicated pin, which implements S WIRE protocol. The auxiliary step-up positive output Auxiliary step-up converter positive voltage voltage is also configured by an external pull- programmable step from 6.6 V to 7.6 V down resistor. Soft-start with controlled inrush default 7.0 V current limit, thermal shutdown and short-circuit Soft-start with inrush current protection protection are integrated functions of the device.
