BD9781HFP
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. Features 1) Minimal external ponents 2) Wide input voltage range: 7 V to 35 V (BD9778F/HFP and BD9781HFP), 7 V to 48 V (BD9001F) 3) Built-in P-ch POWER MOS FET 4) Output voltage setting enabled with external resistor: 1 to VIN 5) Reference voltage accuracy: ±2% 6) Wide operating temperature range: -40˚C to +125˚C (BD9778F/HFP and BD9781HFP), -40˚C to +95˚C (BD9001F) 8) Low dropout: 100% ON Duty cycle 9) Standby mode supply current: 0 µA (Typ.)
