With no synchronous rectifier, the external diode handles the low-side path, which is a cost-effective choice for output currents up to a few amps depending on the external MOSFET and inductor selected. ## Temperature grade and environment Rated for -40°C to 85°C ambient, this controller fits industrial environments: motor drives, outdoor telecom equipment, factory automation panels, and engine-bay electronics. No need to step up to a mil-grade part for these conditions. ## Sourcing and lifecycle The MAX1626ESA+ carries an Active lifecycle status and is ROHS3 compliant.","metaTitle":"MAX1626ESA+ Buck Controller, 300kHz, 8-SOIC","metaDescription":"Maxim MAX1626ESA+ step-down buck controller, 300kHz switching, 3V-16.5V supply, -40°C to 85°C, 8-SOIC.
