STMicroelectronics Special Purpose Regulators STOD14PUR

The STOD14PUR is a dual DC-DC converter designed specifically for powering AMOLED displays, featuring both step-down and inverter converter capabilities. It operates within an input voltage range of 6 V to 13 V and can deliver an output current of 700 mA. The positive output voltage is fixed at 4.6 V, while the negative output voltage can be programmed from -2.4 V to -6.0 V via a single-wire protocol controlled by an external MCU. This converter boasts a typical efficiency of 85% and operates at a switching frequency of 1.6 MHz, allowing for reduced size and value of external components. It includes several protective features such as short-circuit protection, overtemperature protection, and a soft-start function to manage inrush current. The device is packaged in a compact DFN 4x4 mm format with a height of 0.75 mm and a pitch of 0.5 mm, making it suitable for applications in digital photo frames, ultra-mobile PCs, and portable media players. The operating temperature range is from -40 ¬8C to 85 ¬8C, ensuring reliability in various environments.
