The 300kHz fixed switching frequency keeps the magnetics small enough for the 8-SOIC footprint while staying below the AM radio band — a practical choice for industrial control boards that share a chassis with sensitive analog front-ends. ## 100% duty cycle and external FET flexibility With a maximum duty cycle of 100%, the controller can run the external pass element fully on — useful when the input voltage drops close to the output setpoint, as in battery-powered gear riding out a discharge curve. The transistor driver output (no synchronous rectifier on-chip) means the designer picks the N-channel MOSFET for the load current and thermal budget, trading BOM cost against efficiency at light load. An Enable pin allows the regulator to be sequenced or shut down by a system supervisor, pulling the controller into a low-power state without dropping the input rail. The single positive output configuration with a single phase keeps the compensation simple — a Type III network around the error amplifier is the usual starting point for stable loops with ceramic output capacitors. ## Industrial temperature range and SOIC package Surface-mount packaging in tape-and-reel or cut-tape options supports both volume pick-and-place and prototype builds.","metaTitle":"MAX1626ESA+T Buck Controller, 300kHz, 8-SOIC, Active","metaDescription":"MAX1626ESA+T step-down DC-DC controller from Analog Devices. 3V-16.5V input, 300kHz switching, 8-SOIC package.
