24V/1.2A Asynchronous Buck Converter in SOT23-6

BL8095

DESCRIPTION

The BL8095 is a high efficiency current-mode

asynchronous, 24V/1.2A buck converter. Its input

voltage ranges from 4V to 24V and it provides an

adjustable regulated output voltage from 0.810V

to 5.5V while delivering up to 1.2A of output

current.

The switching frequency is set to 1.4MHz, which

works with a inductor as small as 4.7uH. And the

BL8095 will automatically switch between PFM

and PWM mode based on the load current, thus

to enhance the converter efficiency at light load.

BL8095 consists of many protection blocks such

as UVLO, input voltage over voltage protection to

stand much higher input voltage spike, thermal

protection and output short circuit protection.

The BL8095 is available in the tiny SOT23-6

package.
