8-35V 1.5A 1ch Buck converter - BD9870FPS

The BD9870FPS single-channel step-down switching regulator incorporates a Pch MOSFET capable of PWM operation at 900kHz, enabling use of a smaller coil, as well as circuitry that eliminates the need for external compensation - only a diode, coil, and ceramic capacitor are required - reducing board size significantly.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
