BL8095
24V/1.2A Asynchronous Buck Converter in SOT23-6
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.
