BD9870FPS
BD9870FPS is Buck Converter manufactured by ROHM.
8.0V to 35V, 1.5A 1ch Buck Converter with Integrated FET
General Description
The BD9870FPS is a single-channel step-down switching regulator integrated with a P-Channel MOSFET capable of PWM operation at 900 k Hz. It employs the use of smaller coil and circuitry to eliminate the need for external pensation. The circuitry consists only of a diode, coil and ceramic capacitor thus reducing the board size significantly.
