Switching Regulators
with Built-in Power MOSFET
BD9006F/HFP, BD9007F/HFP, BD9009HFP
No.12027ECT35
âOverview
The high-accuracy frequency flexible step-down switching regulator is a switching regulator with built-in POWER MOS FET,
which withstands high pressure. The operational frequency is freely configurable with external resistance. It features a wide
input voltage range (7V~35V) and a high frequency accuracy of ±5% (BD9006F/HFP,BD9009HFP, f=200~500kHz),
Furthermore, an external synchronization input pin enables synchronous operation with external clock.
âFeatures
1) Minimal external components
2) Wide input voltage range: 7Vï½35V
3) Frequency voltage accuracy: ±5%(BD9006F/HFP,BD9009HFP, f=200ï½500kHz)
±20%(BD9007F/HFP)
4) Built-in P-ch POWER MOS FET
5) Output voltage setting enabled with external resistor: 0.8Vï½VIN
6) Reference voltage accuracy: 0.8V±2%
7) Wide operating temperature range: -40âï½+105â
8) Low dropout: 100% ON duty cycle
9) Standby mode supply current: 0µA (Typ.)
10) Oscillation frequency variable with external resistor: 50ï½500kHz
11) External synchronization enabled
12) Soft start function: soft start time fixed to 5ms (Typ.)
13) Built-in overcurrent protection circuit
14) Built-in thermal shutdown protection circuit
15) High-power HRP7 package mounted (BD9006HFP,BD9007HFP,BD9009HFP)
16) Compact SOP8 package mounted (BD9006F,BD9007F)
âApplications
All fields of industrial equipment, such as Flat TV, printer, DVD, car audio, car navigation,
and communication such as ETC, AV, and OA.
