Description

General part information

BD9873CP-V5 Series

The BD9873CP-V5 and BD9874CP-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.
