It drives a single external N-channel MOSFET with a transistor-driver output, making it suitable for isolated and non-isolated power supplies where the output must be above or straddle the input rail. The 75% maximum duty cycle limits the boost ratio in a single stage — for higher ratios, a SEPIC or two-stage topology is needed. ## Supply rail and temperature grade for industrial environments Operating from a 9.5 V to 24 V supply (Vcc/Vdd), the controller runs off a regulated 12 V or 24 V industrial bus without an extra pre-regulator. The enable control pin allows the controller to be sequenced on and off, useful for power-up tracking or fault shutdown in multi-rail systems. No synchronous rectifier is built in — the external diode handles the output stage, which keeps the BOM simple for moderate-current designs. ## Package, footprint, and shelf-life considerations Housed in a 10-TFSOP/MSOP package (3.00 mm width, 0.118\" pitch), the MAX17499BAUB+ is supplied in tube format. The supplier device package is 10-uMAX/uSOP — a common footprint that fits standard 10-pin MSOP land patterns. Store the tubes in a dry environment; the MSOP body is not moisture-sensitive by default, but the reel-less tube format means no moisture-barrier bag is included.","metaTitle":"MAX17499BAUB+ Boost/SEPIC Controller, 50kHz-2.5MHz, 10-uMAX","metaDescription":"MAX17499BAUB+ step-up/step-down controller from Analog Devices.
