BD 系列 7 至 48 V 300 kHz 2 A 表面贴装 降压 开关稳压器 - SOIC-8
Overview
The flexible step-down switching regulator controller is a switching regulator controller designed with a high-withstand-voltage built-in POWER MOS FET, providing a free setting function of operating frequency with external resistor. This switching regulator controller features a wide input voltage range 7 V to 35 V or 7 V to 48 V and operating temperature range -40˚C to +125˚C or
-40˚C to +95˚C. Furthermore, an external synchronization input pin BD9781HFP enables synchronous operation with external clock.
