EPC2071 and EPC2066 EPC9174:40–60 V Input,10–15 V,100 A Output Fixed Conversion Ratio 1.2 kW LLC,⅛-th Brick Size Module Quick Start Guide
■The EPC9174 demonstration board is a 1.2 kW,48 V input to 12 V output LLC converter that operates as a DC transformer with fixed conversion ratio of 4:1.The simplified schematic diagram is shown in Figure 1.It features the 100 V rated EPC2071 and 40 V rated EPC2066 GaN FETs,the uP1966A and LMG1020 gate drivers as well as the Microchip dsPIC33CK32MP102 16-bit digital controller.Other features include:
▲Peak efficiency:97.3 % at 550 W
▲Full-load efficiency:96.3% @ 12 V delivering 100 A output
▲22.9 × 58.4 mm (0.90 × 2.30 inches)
▲Low profile:10 mm total converter thickness without heatsink
▲Temperature rise:72.5°C @ 12 V with 100 A output (with heatsink kit installed)
▲Fixed switching frequency:1 MHz
▲Soft startup into full resistive load
▲High power density:1472 W/in³ (excluding pins)
