STOD32A中文资料300 mA三重DC-DC转换器用于AMOLED显示屏供电数据手册ST规格书

描述 Description

The STOD32A is a triple DC-DC converter for AMOLED display panels. It integrates 300 mA step-up and inverting DC-DC converters plus auxiliary step-up converter. This device is particularly suitable for battery-operated products, in which the major concern is overall system efficiency. Output voltages can be programmed by a dedicated pin, which implements SWIRE protocol. Soft-start with controlled inrush current limit, thermal shutdown and short-circuit protection are integrated functions of the device.
