    Products Detail

    The MIC2172 and MIC3172 are 100kHz switching regulators with 1.25A internal switch rating and 3V to 40V input voltage range. They feature current mode operation, internal cycle-by-cycle current limit, and low external parts count. These controllers operate in most switching topologies including step-up, step-down, inverting, and Cuk configurations. The MIC3172 includes enable/shutdown control with TTL compatibility and <1μA shutdown current, while the MIC2172 offers external frequency synchronization and trim capabilities. Both devices draw 7mA quiescent current and are designed to fit LT1172 sockets.
