MIC2128YML Evaluation Board

Part Number: ADM00770

Summary:

The MIC2128 Evaluation Board is a constant-frequency, synchronous buck controller
featuring a unique adaptive on-time control architecture. The MIC2128 operates over
an input supply range of 4.5V to 75V. The output voltage is adjustable down to 0.6V
with a guaranteed accuracy of ±1%. The device operates with programmable switching
frequency from 270 kHz to

Product Features

    The MIC2128 Evaluation Board:
    • Features soft-start (SS) time selection pin which allows the user to adjust the
    output soft-start time to reduce inrush current from mains during startup
    • Features an auxiliary bootstrap low-dropout (LDO) which improves the system
    efficiency by supplying the internal bias power from the output of the converter. A
    logic level enable (EN) signal can be used to enable or disable the controller.
    • Can start up monotonically into a pre-biased output
    • Features an open drain power good signal (PG) which signals when the output is
    in regulation
    • Operates in discontinuous conduction mode during soft start at light loads
    The basic parameters of the evaluation board are:
    • Input: 7V to 75V (Optimized for 48V)
    • Output: 5V at 5A
    • 300 kHz Switching Frequency (adjustable 270 kHz to 800 kHz)
