DEMO MANUAL DC2641A

DESCRIPTION

LTC7801EUFD

High Input Voltage

Synchronous Buck Converter

Demonstration circuit 2641A is a single output synchro-

nous buck converter featuring the LTC7801EUFD in the

24-lead QFN package. The input voltage range is from

16V to 100V and the output is 12V/10A. The DC2641A is

configured with a sense resistor for overcurrent protec-

tion. Inductor DCR current sensing is optional.

The board has a lot of features including an optional

onboard NMOS LDO for DRVCC, a switch-mode power

supply for EXTVCC, jumper selectable 100% duty cycle

operation in dropout, a mode selector pin that allows

the converter to run in CCM, pulse-skip, adjustable burst

PERFORMANCE SUMMARY

clamp or default Burst Mode® operation, a PGOOD output

voltage monitor and PLLIN for PolyPhase® operation.

The LTC7801 data sheet gives a complete description

of the part, operation and application information and

must be read in conjunction with this demo manual for

DC2641A.
