MAX38642A - 700mA nanoPower Buck Converter

Download the MAX38642A datasheet PDF. This datasheet also covers the MAX38640A variant, as both devices belong to the same 700ma nanopower buck converter family and are provided as variant models within a single manufacturer datasheet.

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.
