The BD9870FPS is a single-channel step-down switching regulator integrated with a P-Channel MOSFET capable of PWM operation at 900 kHz. It employs the use of smaller coil and circuitry to eliminate the need for external compensation. The circuitry consists only of a diode, coil and ceramic capacitor thus reducing the board size significantly. Features Buil.
