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.
FEATURES
Adjustable Output Voltage, Vfb=0.810V Output current is up to 1.2A Range of operation input voltage: 4-24V Input voltage UVLO: 3.7V (voltage decreasing) Input Overvoltage Protection @26V Withstand input voltage spike >30V Operating current at zero load: 0.8mA (typ.) Line regulation: 0.1%/V (typ.) Load regulation: 10mV (typ.) High efficiency, up to 90% Environment Temperature: -20C~85C
