MIC2125YML-T5

MIC2125 and MIC2126 are constant-frequency synchronous buck controllers featuring a unique adaptive ON-time control architecture. The MIC2125/6 operates over an input voltage range from 4.5V to 28V and can be used to supply load current up to 25A . The output voltage is adjustable down to 0.6V with a guaranteed accuracy of ±1%. The device operates with programmable switching frequency from 200kHz to 650kHz.HyperLight Loadarchitecture provides the same high efficiency and ultra-fast transient response as the Hyper Speed Controlarchitecture under the medium to heavy loads. It also maintains high efficiency under light load conditions by transitioning to variable frequency, discontinuous conduction mode operation.The MIC2125/6 offers a full suite of protection features to ensure protection of the IC during fault conditions. These include undervoltage lockout to ensure proper operation under power-sag conditions, internal soft-start to reduce inrush current, "hiccup" mode short-circuit protection, and thermal shutdown.
