EPC9160 Synchronous Buck Converter Reference Design

EPC's EPC9160 is a 9 V to 24 V to dual output 5 V/3.3 V, 15 A synchronous buck converter operating at 2 MHz switching frequency. The EPC9160 features the EPC2055 GaN FET and LTC7890 two-phase analog buck controller with integrated gate drivers from Analog Devices.

The efficiency of the EPC9160 is greater than 93% for 5 V output and 24 V input and, thanks to the high switching frequency, the converter size is very small at only 23 mm x 22 mm for both outputs and an inductor height of only 3 mm.

Applications

• Synchronous buck DC/DC converters
• Automotive consoles
• Power systems requiring small size and very thin profile: computing, industrial, consumer, and telecom power
