Sharge Selects GaN FETs from EPC for High-power USB PD Charger

­Efficient Power Conversion has teamed up with SHARGE Technology (SHARGE) to design a 67 W USB PD charger with a power display screen. The Retro 67 fast charger uses EPC’s 100 V GaN FET, EPC2218, which can deliver 231 A pulsed current in a tiny footprint of 3.5 mm x 1.95 mm offering designers a significantly smaller, more efficient device than silicon MOSFET for USB PD fast chargers.

EPC2218 provides SHARGE’s All-GaN fast charger with higher efficiency, state-of-the-art power density and lower system cost.

The SHARGE Retro 67 supports 67 W of power output, providing a full-speed charging experience for the latest high-power laptops. The charger has three USB-C ports, to support multiple device charging.

The Retro 67 uses EPC2218 to achieve the most efficient power conversion, reducing product size and enabling a PCBA power density of up to 1.39 W/cm³ and an overall power density of 0.85 W/cm³ with 90 V AC input. The overall conversion efficiency of the SHARGE Retro 67 fast charger is 92.16% with 230 V AC input.

The Retro 67 charger is designed to resemble a traditional desktop computer with an LED matrix panel displaying digital rain animations and charging power for mobile phone, tablets, and laptops, incorporating fun with functionality.
