Microchip Technology MIC28517 Evaluation Board

Microchip Technology MIC28517 Evaluation Board is designed to evaluate the MIC28517 synchronous buck switcher over 4.5V to 70V input supply range. The device operates from 270kHz to 800kHz programmable switching frequency range. This evaluation board comes with two selectable modes CCM or HLL to improve efficiency at light loads.

Features

4.5V to 70V (optimized for 48V) (V_in) input voltage range
0.6V to 12V (V_out) selectable through jumper J10 @ 8A (default option is set to 5V)
270kHz to 800kHz switching frequency (adjustable from 270kHz to 800kHz)
MODE selection trough jumper J6, which allows the user to select either the CCM or HLL mode of operation
Open-drain Power Good signal (PG), which signals when the output is in regulation

Logic level Enable (EN) signal that can be used to enable or disable the controller
Programmable current limit
“Hiccup” mode short-circuit protection
Thermal shutdown
Safe start-up into pre-biased output
