Product Overview
The BD9870FPS-E2 is a single-channel step-down switching regulator Buck Converter with Integrated FET, a P-channel MOSFET capable of PWM operation at 900kHz. 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.
- Built-in P-channel FET ensures high efficiency
- Output voltage adjustable via external resistors
- Over-current and thermal shutdown protection circuits built-in
- ON/OFF control via STBY pin
- Ceramic output capacitor compatibility
