Overview

Single-chip Type with Built-in FET Switching Regulator Series Simple Step-down Switching Regulators with Built-in Power MOSFET BD9873CP-V5,BD9874CP-V5 No.
09027EBT39 ● Description The BD9873,74CP-V5 single-channel step-down switching regulator incorporates a Pch MOSFET capable, as well as circuitry that eliminates the need for external compensation – only a diode, coil, and ceramic capacitor are required – reducing board size significantly.
●Features 1) Maximum switching current : 1.
5A, 3.
0A 2) Built-in Pch FET ensures high efficiency 3) Output voltage adjustable via external resistors 4) High switching frequency : 110kHz (fixed) 5) Soft start time : 4ms (fixed) 6) Over current and thermal shutdown protection circuits built in 7) ON/OFF control via STBY pin ●Applications TVs, printers, DVD players, projectors, gaming devices, PCs, car audio/navigation systems, ETCs, communication equipment, AV products, office equipment, industrial devices, and more.
