Single-chip Type with built-in FET Switching Regulator Series  
Flexible Step-down  
Switching Regulators  
with Built-in Power MOSFET  
BD9778F, BD9778HFP, BD9001F, BD9781HFP  
No.10027EBT41  
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 components  
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: 2ꢀ  
6) Wide operating temperature range: -40˚C to +125˚C (BD9778F/HFP and BD9781HFP),  
-40˚C to +95˚C (BD9001F)  
8) Low dropout: 100ꢀ ON Duty cycle  
9) Standby mode supply current: 0 µA (Typ.) (BD9778F/HFP and BD9781HFP), 4 µA (Typ.) (BD9001F)  
10) Oscillation frequency variable with external resistor: 50 to 300 kHz (BD9001F),  
50 to 500 kHz (BD9778F/HFP and BD9781HFP)  
11) External synchronization enabled (only on the BD9781HFP)  
12) Soft start function : soft start time fixed to 5 ms (Typ.))  
13) Built-in overcurrent protection circuit  
14) Built-in thermal shutdown protection circuit  
15) High power HRP7 package mounted (BD9778HFP and BD9781HFP)  
Compact SOP8 package mounted (BD9778F and BD9001F)  
Applications  
All fields of industrial equipment, such as Flat TV , printer, DVD, car audio, car navigation,  
and communication such as ETC, AV, and OA.
