BL8038中文资料降压型DC/DC转换器(DC/DC Step-down Converter)数据手册Belling规格书

描述 Description

The BL8038 is a high-efficiency, DC-to-DC step-down switching regulators, capable of delivering up to 1A of output current. The device operates from an input voltage range of 2.6V to 5.5V and provides an output voltage from 0.6V to Vin.

Working at a fixed frequency of 2MHz allows the use of small external components, such as ceramic input and output caps, as well as small inductors, while still providing low output ripples. This low noise output along with its excellent efficiency achieved by the internal synchronous rectifier, making BL8038 an ideal replacement for large power consuming linear regulators.

Internal soft-start control circuitry reduces inrush current. Short-circuit and thermal shutdown protection improves design reliability.

The BL8038 is available in SOT23-5.
