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 FEATURES  Adjustable Output Voltage, Vfb=0.
