Datasheet 8.0V to 35V, 1.5A 1ch Buck Converter with Integrated FET BD9870FPS General Description 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  Built-in P-Channel MOSFET for High Efficiency  Adjustable Output Voltage Via External Resistors  Soft-Start Time: 5ms (Fixed)  Built-In Over-Current Protection and Thermal Shutdown Circuits  ON/OFF Control Via STBY Pin  Ceramic Output Capacitor Compatibility Key Specifications  Input Voltage Range: 8.0V to 35.
