EPC – POWER CONVERSION TECHNOLOGY LEADER | EPC-CO.COM | ©2021 | | 2
DESCRIPTION
The EPC9160 is a 9–24 V to dual output 5 V/ 3.3 V 15 A synchronous
buck converter. EPC9160 is designed with EPC2055 enhancement
mode eGaN® FET and LTC7890 two phase analog buck controller with
integrated GaN drivers. EPC9160 features:
• Wide V
IN
range: 9 V-24 V
• Analog controller with integrated driver optimized for eGaN® FET
• High eciency: >93 % for 5 V output and 24 V input
• High Switching frequency (2 MHz) and small size (23 mm x 22 mm
power stage)
• Recongurable light load operating mode and adjustable dead time
• Other functions:
o UVLO
o Over-current protection
o Power good output
o External synchronization

[1] The maximum current capability is dependent on thermal conditions. The FET
temperature should be monitored to ensure the maximum temperature does not
exceed the rating in the datasheet, in particular when the input voltage is higher
than 54 V, the maximum output current will be reduced.
