No.09027EAT35

●Overview

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, BD9006HFP; f=200~500kHz), Furthermore,

an external synchronization input pin enables synchronous operation with external clock.

●Features

1) Minimal external components

2) Wide input voltage range: 7V～35V

3) Frequency voltage accuracy: ±5%(BD9006F,BD9006HFP ; f=200～500kHz)

±20%(BD9007F, BD9007HFP)

4) Built-in P-ch POWER MOS FET

5) Output voltage setting enabled with external resistor: 0.8V～VIN

6) Reference voltage accuracy: 0.8V±2%

7) Wide operating temperature range: -40℃～+105℃

8) Low dropout: 100% ON duty cycle

9) Standby mode supply current: 0µA (Typ.)

10) Oscillation frequency variable with external resistor: 50～500kHz

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)

16) Compact SOP8 package mounted (BD9006F,BD9007F)

●Applications

All fields of industrial equipment, such as Flat TV, printer, DVD, car audio, car navigation,

and communication such as ETC, AV, and OA.
