STOD03ASTPUR Description

Short technical summary and product information.

The STMicroelectronics STOD03ASTPUR is a dual DC-DC converter specifically designed for powering Active Matrix AMOLED displays. It integrates both a step-up and an inverting DC-DC converter, making it suitable for battery-operated devices where system efficiency is critical.

 

This converter operates within an input voltage range of 2.5 V to 4.5 V. It provides a fixed positive output voltage of 4.6 V and a programmable negative output voltage that can be adjusted from -2.4 V to -5.4 V in 100 mV steps via a SWIRE interface. The device features synchronous rectification for both converters, contributing to its typical efficiency of 85%.

 

For light load conditions, the STOD03ASTPUR utilizes a pulse skipping mode, and at medium to high loads, it operates in a 1.5 MHz PWM mode. This high switching frequency allows for smaller external components. The device includes an Enable pin for shutdown mode, reducing quiescent current to less than 1 µA, and features soft-start with inrush current protection, overtemperature protection, and short-circuit protection.

 

The STOD03ASTPUR is available in a compact DFN12L package measuring 3 x 3 mm with a height of 0.6 mm, suitable for surface mount applications. Its applications include cellular phones, camcorders, digital still cameras, and multimedia players.
