LTC7806 | 6V to 36V Input, 24V, 10A Output, Synchronous Boost Regulator with Input Current Monitor

Product Details

Demonstration circuit 2951A is a boost regulator featuring the LTC7806. The DC2951A operates from a 6V to 36V input voltage range and generates 24V, 10A output from a 12V input. When VIN ≥ 24V, VOUT follows VIN. Also, the LTC7806 has precision voltage reference, which can generate an output voltage with 2% tolerance over the full operating conditions. The 350kHz switching frequency operation results in small and efficient circuit. The converter achieves over 95% efficiency with 10A load. The demonstration circuit can be easily modified to regulate different output voltages.

The DC2951A provides a high performance cost-effective solution for generating output voltages up to 36V from inputs as low as 5V.

The LTC7806 data sheet gives a complete description of this part, its operation and application information and must be read in conjunction with the demo manual.
