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
