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.

Maximum switching current : 1.5A

Built-in Pch FET ensures high efficiency

Output voltage adjustable via external resistors

High switching frequency : 900kHz (fixed)

Soft start time : 5ms (fixed)

Overcurrent and thermal shutdown protection circuits built in

ON / OFF control via STBY pin

Ceramic output capacitor compatibility

Small surface mount TO252S-5 package
