It drives an external transistor switch — the internal controller handles the loop compensation, soft start, and frequency control, while the power path stays external for flexibility in the FET selection. Supply voltage spans 2.7 V to 15.5 V on Vcc/Vdd, making it usable from a single Li-ion cell up to a regulated 12 V rail. The output can be configured as positive or negative, which covers inverting buck-boost designs for bipolar analog supplies. Operating temperature is rated 0°C to 70°C — commercial-grade silicon, so it is suited for bench equipment, telecom line cards, and indoor industrial control, not for under-hood or outdoor ambient above 70°C. ## Package and supply rail considerations Housed in a 20-SSOP (0.209-inch body width, 5.30 mm wide), the MAX741UCAP-T uses a surface-mount footprint common to many Analog Devices power controllers. No synchronous rectifier is integrated — the design relies on an external Schottky diode for the catch rectifier. This is typical of older-generation controllers; the efficiency gain from synchronous rectification is absent, but the controller cost and BOM simplicity can favour non-sync designs in lower-power or cost-sensitive rails. Clock sync is available as a feature — the switching frequency can be locked to an external clock, which helps manage beat-frequency noise in multi-rail systems where several converters share a board. ## Sourcing and compliance status Lifecycle is marked Active by the manufacturer — the MAX741UCAP-T remains a current production part with no announced end-of-life. No stock-holding claim — quoted per RFQ.","metaTitle":"Analog Devices MAX741UCAP-T Switching Controller, Buck/Boost","metaDescription":"MAX741UCAP-T step-up/step-down switching controller from Analog Devices.
