Description
Demonstration circuit 2517A features the LT®8362 in a CUK configuration. It operates with a switching frequency of 2MHz and is designed to convert a 4.5V to 42V source to –12V, with up to 1A output current (depending on input voltage). Refer to Figure 4 for load current versus input voltage. The LT8362 can operate with inputs as high as 60V, however, in this demo circuit, the input is limited by the maximum voltage across the switch (|VOUT| + VIN <60V).The demo board contains a selectable jumper, JP1, to aid in the selection of the desired Sync pin mode of operation. The default setting is Burst Mode® operation.This layout is optimized for good EMI performance and small solution size. Input and output filters and an optimized power switching 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.
