The 300 kHz fixed switching frequency keeps external inductor and capacitor sizes small — a 10 µH to 47 µH inductor and a low-ESR ceramic output cap are typical for most designs. No synchronous rectifier is integrated, so the external Schottky diode's forward voltage and thermal handling set the efficiency ceiling. In a boost configuration from 3.3 V to 12 V at 100 mA, expect efficiency in the low 80s percent with a good Schottky. ## 8-SOIC footprint and supply posture The part is supplied in tube packaging — typical for prototype and low-volume builds.","metaTitle":"MAX629ESA+ Analog Devices DC-DC, Boost/Flyback/SEPIC, 500mA","metaDescription":"MAX629ESA+ from Analog Devices — Active, multi-topology DC-DC converter, 500 mA output, ±28 V max, 8-SOIC.
