General Description
The MAX3864xA/B are nanoPower family of ultra-low 330nA quiescent current buck (step-down) DC-DC converters operating from 1.8V to 5.5V input voltage and supporting 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 MAX3864xA/B are ideal for battery applications where long battery life is a must.
The MAX3864xA/B family utilizes a unique control scheme that allows ultra-low quiescent current and high efficiency over a wide output current range. 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 .
