Overview
The MIC28515 75V/5A HLL Step Down Evaluation Board allows for the evaluation of the MIC28515 Syncronous Buck Switcher over an input supply range of 4.5V to 75V while providing 5A. The device operates with a programable switching frequency from 270kHz to 800kHz and with two selectable modes: CCM or HLL to improve efficiency at light loads.
-Input: 10V to 75V (optimized for 48V)
-Output: 0.8V, 1.2V, 2.5V, 3.3V, 5V or 12V Selectable through jumper J10 at 5A (default option is set to 5V)
-300 kHz Switching Frequency (adjustable from 270 kHz to 800 kHz)
-Features MODE selection trough jumper J6, which allows the user to select either the CCM or HLL mode of operation.
-Features an open-drain Power Good signal (PG), which signals when the output is in regulation.
-Features a logic level Enable (EN) signal that can be used to enable or disable the controller.
