1.2A 1.5MHz 7V Synchronous Buck Converter

BL8021

DESCRIPTION

The BL8021 is a high-efficiency, DC-to-DC step-

down 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. Internal

soft-start control circuitry reduces inrush current.

Short-circuit

and

thermal-overload

protection

improves design reliability.

BL8021 is housed in a SOT23-5 Package
