DEMO MANUAL DC2716A

DESCRIPTION

LT8364

Demo circuit 2716A features the LT8364 in boost con-

figuration. It is designed to convert a 4.5V to 20V source

to 24V, with up to 1.6A, depending on input voltage, with

a switching frequency of 2MHz. The LT8364 can operate

with inputs as high as 60V, however, in this demo circuit,

the input is limited by the level of the output voltage. Refer

to Figure 4 for load current versus input voltage.

The demo board contains a selectable jumper, JP1, to aid

in the selection of the desired Sync pin mode of operation.

This layout is optimized for good EMI performance and

solution size. Input and output filters and an optimized

PERFORMANCE SUMMARY

hot loop, comprised of C11 and C12 are necessary to pass

CISPR 25 Class 5 emissions, and are added by default.

These components can be excluded in applications not

requiring noise immunity. Radiated emissions plots are

included in this manual.

The data sheet gives a complete description of the device,

operation and application information. The data sheet

must be read in conjunction with this demo manual.
