Single-chip Type with built-in FET Switching Regulator Series
Flexible Step-down
Switching Regulators
with Built-in Power MOSFET
BD9006F/HFP, BD9007F/HFP, BD9009HFP
No.12027ECT35
●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/HFP,BD9009HFP, f=200~500kHz),
Furthermore, an external synchronization input pin enables synchronous operation with external clock.
●Features
