BL9382
18V (30V spike) 2A Synchronous Buck Converter
DESCRIPTION
The BL9382 is a high efficiency current-mode
synchronous, 18V/2A buck converter. Its input
voltage ranges from 4.5V 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.
BL9382 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 BL9382 is available in the SOP8 and ESOP8
(with exposed pad for heat dissipation) package
