EL SEGUNDO, Calif.—  March 2023 – Efficient Power Conversion (EPC), the world’s leader in enhancement-mode gallium nitride FETs and ICs, 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.

As an example of the contribution to performance GaN devices can make to one of these mainstream applications, a traditional silicon application, the 12 V – 1 V point-of-load (POL) DC/DC converter will be examined. An eGaN IC based 12 V to 1 V, 12 A load converter yielding a peak efficiency of 78% at 5 MHz with a power density of at least 1000 W/in³, all with a cost below $0.20 per watt will be shown
