Introduction
The LM5088 evaluation board is designed to provide the design engineer with a fully functional power
converter based on Emulated Current Mode Control to evaluate the LM5088 controller IC. The LM5088
evaluation board is available in two versions (like the LM5088 controller): the LM5088-1 evaluation board
provides ±5% oscillator frequency dithering to reduce EMI and the LM5088-2 evaluation board provides
hiccup mode restart to reduce over load stress. Both the evaluation boards share the same layout except
for silkscreen. The printed circuit board consists of 2 layers, 2 ounce of copper top and bottom and the
board size is 2.55 × 1.5 × 0.5 inches.
