Output can be set from 0.9 V up to 32.4 V via an external feedback divider. The 1 A continuous output current is delivered with an integrated synchronous rectifier, which eliminates the need for an external catch diode and improves efficiency at low output voltages. ## Switching frequency and inductor selection At the lower end, the inductor is physically larger but switching losses are lower — a good fit for thermally constrained enclosures. At 2.2 MHz, the inductor shrinks to a small footprint (e.g., 2.2 µH), which suits space-limited designs but pushes more loss into the internal FETs. The frequency choice also sets the output ripple and the loop compensation values.","metaTitle":"MAX17630CATE+ Buck Regulator, 1A, 4.5-36V, TQFN","metaDescription":"Analog Devices MAX17630CATE+ step-down buck regulator, 1A output, 4.5-36V input, adjustable output, 16-TQFN (3x3mm).
