Analog Devices MAX38640 | Demoboard MAX38640AEVK-UDFN

Beschreibung

The MAX38640–MAX38643 are nanoPower family of ultra-low 330nA quiescent current buck (step-down) DC-DC converters that operate from 1.8V to 5.5V input voltage and support load currents of up to 175mA, 350mA, 700mA with peak efficiencies of 96%. While in shutdown, there is only 5nA of shutdown current. The devices offer ultra-low quiescent current, small total solution size, and high efficiency throughout the load range. The MAX38640–MAX38643 are ideal for battery applications where long battery life is a must.The MAX38640–MAX38643 family utilizes a unique control scheme that allows ultra-low quiescent current and high efficiency over a wide output current range. The MAX38642 excludes active discharge resistor in shutdown which allows the output to be regulated or held high by another source or by the charged output capacitor.The MAX38640–MAX38643 devices are offered in a space-saving 1.42mm x 0.89mm 6-pin WLP (2 x 3 bump, 0.4mm pitch), as well as a 2mm x 2mm, 6-pin µDFN package. All parts are specified over the -40°C to +85°C extended temperature range.
