BD9873CP-V5 - Simple Step-down Switching Regulators

General 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.

Key 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.
