TECHNICAL NOTE
Single-chip Type with Built-in FET Switching Regulator Series
Simple Step-down Switching Regulator
with Built-in Power MOSFET
BD9870FPS
● Description
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.
●Features
1. Maximum switching current: 1.5A
2. Built-in Pch FET ensures high efficiency
3. Output voltage adjustable via external resistors
4. High switching frequency: 900kHz (fixed)
5. Soft start time: 5ms (fixed)
6. Overcurrent and thermal shutdown protection circuits built in
7. ON/OFF control via STBY pin
8. Ceramic output capacitor compatibility
9. Small surface mount TO252S-5 package
●
Applications
TVs, printers, DVD players, projectors, gaming devices, PCs, car audio/navigation systems, ETCs, communication equipment, AV
products, office equipment, industrial devices, and more.
