BL8021 1.2A 1.5MHz 7V Synchronous Buck Converter DESCRIPTION The BL8021 is a high-efficiency, DC-to-DC stepdown switching regulators, capable of delivering up to 1.2A of output current. The device operates from an input voltage range of 2.6V to 7.0V and provides an output voltage from 0.6V to VIN, making the BL8021 ideal for low voltage power conversions. Running at a fixed frequency of 1.5MHz 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 BL8021 an ideal green replacement for large power consuming linear regulators.
