General Description

The MAX15020 high-voltage step-down DC-DC converter operates over an input voltage range of 7.5V to 40V. The device integrates a 0.2Ω high-side switch and is capable of delivering 2A load current with excellent load and line regulation. The output is dynamically adjustable from 0.5V to 36V through the use of an external reference input (REFIN). The MAX15020 consumes only 6μA in shutdown mode.
