Synchronous rectification is built in — the low-side FET replaces the external Schottky diode, keeping efficiency above 90 % across most of the load range, especially at lower output voltages where the diode drop would otherwise dominate conduction loss. ## Switching frequency and inductor selection The switching frequency is programmable from 380 kHz to 2.45 MHz via a single resistor. Running at the low end (380 kHz) minimises switching losses and allows a larger inductor for lower ripple current — useful when the load is steady and efficiency is the priority. At the high end (2.45 MHz) the inductor shrinks to a 1 µH or 2.2 µH footprint, saving board area at the cost of slightly higher FET switching loss. For a 3.5 A load at 12 V in to 3.3 V out, the junction temperature stays under 100 °C with a 2 oz copper, 4-layer board and adequate via stitching under the pad — no heatsink required.","metaTitle":"MAX17633CATP+ Analog Devices Buck Regulator, 3.5 A, 36 V","metaDescription":"Active-production step-down regulator from Analog Devices. 4.5-36 V input, 3.5 A output, adjustable 0.9-32.4 V.
