The STMicroelectronics STOD03BTPUR is a specialized dual DC-DC converter with an integrated LDO, specifically designed for powering active matrix AMOLED displays in portable devices. It combines step-up and inverting DC-DC converters, making it suitable for battery-operated products where system efficiency is critical.
The device operates within an input voltage range of 2.3 V to 4.8 V and delivers a minimum output current of 150 mA. It features a fixed 4.6 V positive output from the LDO post-regulator, ensuring line and load transient response with minimal output voltage ripple for stable picture quality. The negative output voltage is programmable from -2.4 V to -5.4 V via a SWIRE interface.
With a typical efficiency of 82% and operating in pulse skipping mode at light loads or PWM mode at 1.5 MHz for higher loads, the STOD03BTPUR helps reduce external component size and power consumption. It includes features like soft-start with inrush current protection, overtemperature protection, and true shutdown mode, reducing quiescent current to less than 1 µA. The operating temperature range is -40 °C to 85 °C.
The STOD03BTPUR is available in a compact 12-DFN (3x3) package, suitable for surface mount applications.
