NCP13994MM360GEVB 360 W PFC and LLC Power Supply Evaluation Board
概览
The NCP13994MM360GEVB is a 360 W AC-DC all-in-one power-supply evaluation board for computers, server power supplies and similar equipment requiring a regulated 12 V input rail. The design combines the NCP1618 multimode PFC controller, NCP13994 current-mode LLC resonant controller, NCP4318 synchronous rectifier controller and NCP431 programmable shunt regulator in a complete power-conversion platform. Operating from 90 to 265 Vac, the board delivers up to 12 Vdc at 30 A.
The NCP1618 PFC stage supports near-unity power factor and low input-current distortion, while the NCP13994 controls the half-bridge LLC stage and integrates 700 V gate drivers. Secondary-side synchronous rectification using the NCP4318 reduces conduction losses, and the NCP431 provides output-voltage regulation through the isolated feedback loop. Coordinated operating and skip modes support high efficiency, fast transient response and low no-load power consumption.
应用
- All-in-one computer power supplies requiring a compact, regulated 12 Vdc rail with high output-current capability.
- Server, computing and networking power supplies using a PFC front end followed by an isolated LLC conversion stage.
- Industrial AC-DC power systems requiring wide-range mains input, high efficiency, synchronous rectification and low standby consumption.
特性
- High efficiency across load range. Excellent no load and ultra-light load power consumption
- Small form factor design
- Uses the NCP1618 multimode PFC controller, which transitions among DCM, frequency-clamped CrM and CCM according to line and load conditions and enters soft-skip mode at very light loads.
- Incorporates various protections including low main, overload and thermal protection
