BL8092
18V (30V spike)2.5A Synchronous PFM/PWM Buck Converter
DESCRIPTION
The BL8092 is a high efficiency current-mode
synchronous, 18V/2.5A buck converter. Its input
voltage ranges from 3.5V to 18V and it provides
an adjustable regulated output voltage from
0.923V to 15V while delivering up to 2A of output
current.
The internal synchronous switches increase
efficiency and eliminate the need for an external
Schottky diode. The switching frequency is set to
340KHz. And the BL8092 will automatically switch
between PFM and PWM mode based on the load
current, thus to enhance the converter efficiency
at light load.
BL8092 consists of many protection block such as
UVLO, input voltage over voltage protection to
stand much higher input voltage spike, thermal
protection and output short circuit protection.
The BL8092 is available in the SOP8 and ESOP8
(with exposed pad for heat dissipation) package.
