MAX17270/MAX17271 3-Output Switching Regulators

Analog Devices MAX17270/MAX17271 3-Output Switching Regulators are ideal for wearable applications needing efficient regulation of multiple power supplies in a tiny space. The regulators use a buck-boost architecture that regulates three outputs using a single, small 2.2µH inductor with efficiencies of up to 85%. The result is smaller board space with better total system efficiency than equivalent power solutions using one buck and linear regulators. Analog Devices MAX17270/MAX17271 3-Output Switching Regulators have a supply current of 0.85µA when only one output is enabled, plus 0.2µA for each additional output enabled.
