The adjustable version uses a resistor divider on the FB pin; the fixed versions eliminate two resistors from the BOM. The integrated synchronous rectifier replaces the external Schottky diode found in older buck designs. At 3A output and 3.3V in to 1.8V out, the efficiency gain over a diode-based converter is roughly 3-5% — enough to drop the junction temperature by 8-10°C in a sealed enclosure. ## Package, temperature grade, and compliance The surface-mount package suits standard reflow profiles with a 260°C peak.
