MIC2125 Datasheet, PDF (11/34 Pages) Microchip Technology – 28V Synchronous Buck Controllers Featuring Adaptive ON-Time Control

MIC2125/6
Note: Unless otherwise noted, V_IN = 12V, FREQ = 350 kHz.
*Note: For Case Temperature graphs: The temperature measurement was taken at the hottest point on the MIC2125/6
case mounted on a 5 square inch PCBn. Actual results will depend upon the size of the PCB, ambient temperature and
proximity to other heat emitting components.
