LM2793 Evaluation Board
The LM2793 Evaluation Board may be used to test and
evaluate a typical LM2793 application circuit. The layout
includes extra large pads for all capacitors and White LEDs
(D
accomodate different case sizes. The layout of the board is
recommended as a guide for end-use board design.
