    Products Detail

    The MIC2129 is a constant-frequency synchronous buck controllers featuring a unique adaptive ON-time control architecture. The MIC2129 operates over an input voltage range from 4.5V to 100V and can be used to supply load current up to 25A (Thermally Limited) . The output voltage is adjustable down to 0.6V with an accuracy of ±1%. The device operates with programmable switching frequency from 100kHz to 800kHz. The MIC2129 controller offers three selectable gate drive voltages (5.2V, 7.5V, 10.5V) to enable the use of logic level or standard FETS to ensure optimal efficiency. The high voltage bootstrap diode is also integrated in this controller saving overall solution size and cost. The other key features of the MIC2129 are remote sense, integrated bootstrap LDO's, adjustable soft start, selectable light load operating modes, precision enable, selectable current limit modes (Hiccup, Latch-up, Cycle by cycle), output OVP protection, Power Good and thermal shut down. The MIC2129 is offered in a 24 pin QFN and as well as TSSOP packages.
