EPC9149: 36 - 60 V Input, 9 - 15 V Output,83 A Output Fixed Conversion Ratio 1 kW LLC, 1/8th Brick size Module Quick Start Guide
The EPC9149 demonstration board is a 1 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 EPC2218 and 40 V rated EPC2024 GaN FETs, the uP1966A and LMG1020 gate drivers as well as the Microchip dsPIC33CK32MP102 16-bit digital controller. Other features include:
■Peak efficiency: 97.5 % at 400 W
■Full-load efficiency: 96.7% @ 12 V delivering 83.3 A output
■22.9 × 58.4 mm (0.90 × 2.30 inches)
■Low profile: 10 mm total converter thickness without heatsink
■Temperature rise: 70 °C @ 12 V with 83.3 A output (with heatsink kit installed
■Fixed switching frequency: 1 MHz
■Soft startup into full resistive load
■High power density: 1227 W/in3 (excluding pins)
