BL8038

1A 2MHz 5.5V Synchronous Buck Converter

DESCRIPTION

FEATURES

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.

•

High efficiency: up to 97%

Output current: up to 1A

2MHz switching frequency

Low dropout 100% duty operation

Internal compensation and soft-start

Current mode control

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.

Reference 0.6V

Logic control shutdown (I_Q<1uA)

Thermal shutdown, UVLO

Available in SOT23-5

APPLICATIONS

•

Cellular phones

Digital cameras

Internal soft-start control circuitry reduces inrush

current. Short-circuit and thermal shutdown

protection improves design reliability.

MP3 and MP4 players

Set top boxes

Wireless and DSL modems

USB supplied devices in notebooks

Portable devices

The BL8038 is available in SOT23-5.
