TRANSPHORM 100W TPA1001C02-V1.2 Power Adapter

Power Adapter Description

This design guide of the Transphorm GaN and Onsemi NCP1623A & NCP1342 controller reference design board describes a 100 W, average efficiency up to 91.93%, with programmable output voltage (5 V/5 A, 9 V/5 A, 15 V/5 A, 20 V/5 A). The power supply uses PFC controller NCP1623A collocation Transphorm GaN TP65H150LSG (650 V SuperGaN FET), Plus the Quasi-Resonant Flyback controller NCP1342 Collocation TP65H300G4LSG (650 V SuperGaN FET). This design shows high power density and efficiency. This document contains the power supply specification, schematic, bill-of-materials, transformer documentation, printed circuit layout, and performance data.

Features

• Integrated Transphorm GaN TP65H150LSG for PFC controller topology
• Integrated Transphorm GaN TP65H300G4LSG for flyback converter topology
• Board-end over 91% Efficiency(90VAC/20V)
• Flat Efficiency Across Universal (90-264 VAC) Input Voltage and Load
• Tight Switching Frequency Regulation for Improved Input EMI Filter Utilization
• Up to 200KHz Switching Frequency Operation
• OTP, UVLO, OPP and OSC Protections
• < 100mW (230Vac) No Load Power Consumption of the IC
• Up to 100W Output Power

Applications

• High-Power-Density USB-PD AC/DC Power Supplies

Warning

1. Caution – High Voltage Operation: Lethal high voltages are present when this evaluation board is powered from AC mains. Improper contact with high voltages could lead to electrical shock, burn and/or fire hazards, risking property damage, personal injury, and death.
2. Evaluation Purpose Only: This evaluation board is intended for evaluation purposes only and not for commercial use. Care must be taken when testing the board, and an isolation transformer should be utilized.
3. Patents: The evaluation board design, along with circuits shown in this test report, may be covered by one or more U.S. and foreign existing/pending patents.

Schematic

Circuit Description

Input Protection
The design incorporates a slow-acting input fuse (F101) as a form of protection in case of destructive failure of any of the downstream components.

EMI Filtering
To meet the target EN55022 conducted EMI specification with sufficient margin with the least number of components and the highest power processing efficiency, the design utilizes an input filter consisting of an X-capacitor (CX101) and a single common- mode choke (LF101,LF102) as well as transformer (T1) construction for better EMI performance.
