ROHM Semiconductor
Single-chip Type with built-in FET Switching Regulator Series
● 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.
