Onsemi NCP13994 | Demoboard 1kW TPFC TND6454/D

1 kW Universal Input 48 V Output Power Supply Reference Design

Overview

TopologyPower Factor Correction
Input voltage110-230 V
Output 148 V

Description

This reference design gives basic information about a highswitching frequency and high efficiency AC/DC power supply reference design that provides 110 V AC (230 V AC) to 48 VDC output conversion. The power supply implements current mode control technique with enhanced load transient response. Furthermore, this design includes a fixed frequency, Continuous Conduction Mode (CCM) Power Factor Correction (PFC) control technique designed to drive the bridgeless Totem Pole PFC (TPFC) topology. The GaN switches on the primary side enable high operating frequency while synchronous rectification on the secondary side maximize efficiency.This reference design provides brief information about controllers’ implementation into design, their interconnections and cooperation. For more comprehensive information please refer to datasheets of individual parts that have been used. Please use links in literature section to get detail technical information about NCP1681, NCP13994, NCP4306, NCP4307, NCP1343, NCV8730, NCP718, NCP431 circuits.The NCP13994 is a high−performance current mode LLC controller for half bridge resonant converters. This controller implements 700 V gate drivers, simplifying layout and reducing external component count. The controller is capable to drive high switching frequency and high−power application as well as standard low power consumer applications. In applications where a PFC front stage is needed, the NCP13994 features an output that can be used to drive the PFC controller. This feature together with quiet skip mode technique further improves light load efficiency of the whole application. The controller provides a suite of protection features allowing safe power supply operation in any application.
