Lower frequencies improve efficiency but need a bigger inductor; higher frequencies shrink the magnetics at the cost of some switching loss. For a 50 mA rail, the inductor is small either way, but the flexibility matters if you're trying to keep the switcher out of a sensitive frequency band. The -40°C to 125°C junction temperature rating covers industrial enclosures and under-hood automotive environments. If the board sits near a hot motor or in direct sunlight, this part won't derate early. ## Lifecycle and compliance It's ROHS3 compliant, so it passes the material restrictions for EU and most global markets without an exemption hunt.","metaTitle":"MAX17551AUB+ Himalaya Buck Regulator, 4V-60V Input, 50mA","metaDescription":"MAX17551AUB+ step-down regulator from Maxim's Himalaya series. 4V to 60V input, 50 mA output, adjustable down to 0.8V.
