STOD02 Dual DC-DC Converter

STMicroelectronics and Digi-Key introduce a dual DC-DC converter for powering AMOLED display

Image of STMicroelectronics' STOD02 Dual DC-DC ConverterThe STOD02 from STMicroelectronics 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.

The high frequency allows a reduction in the value and number of external components to just six. The enable pin allows the device to turn off, thus reducing the current consumption to less than 1 µa. The negative output voltage can be programmed by an MCU through a dedicated pin, which implements single-wire protocol. Soft-start with controlled inrush current limit and thermal shutdown are integrated functions of the device.

Features Applications
  • Synchronous rectification for both DC-DC converters
  • Programmable negative voltage by S-wire from -2.3 V to -5.9 V
  • Pulse skipping mode in light load condition
    • (lo < 10 mA)
  • 1.6 MHz PWM mode control switching frequency
    • (lo > 10mA)
  • True shutdown mode
  • Fast outputs discharge circuit after shutdown
  • Active Matrix Organic LED power supply (AMOLED)
  • Mobile phones
  • PDAs
  • Camcorders
  • Digital still cameras
