LTC7891 High Frequency Step-Down Supply with GaN FETs

Analog Devices Inc.

Description

Demonstration circuit 2995A is a buck regulator featuring the LTC7891. The DC2995A operates from a 36V to 72V input voltage range and generates a 12V, 20A output. The LTC7891 has a precision voltage reference which can generate an output voltage with 2% tolerance over the full operating conditions. The 500kHz switching frequency operation results in a small and efficient circuit. The converter achieves over 96% efficiency with 20A load. The demonstration circuit can be easily modified to regulate output voltages from 0.8V to 60V. The DC2995A provides a high performance cost-effective solution for generating a 12V output. The LTC7891 data sheet gives a complete description of this part, its operation and application information and must be read in conjunction with the demo manual.
