Overview

Description

The MAX1638VRM evaluation kit (EV kit) provides a digitally programmable output voltage between 1.3V and 3.5V from a 5V input supply. It delivers up to 14A output current with greater than 90% efficiency. The MAX1638 features 1% output accuracy as well as 1% AC-load regulation. The EV kit operates at a 600kHz switching frequency and has excellent dynamic response to correct for fast output transients.

A separate test-fixture PC board emulates a system motherboard and contains a 22µF ceramic capacitor that models the local CPU bypass capacitors. The test fixture also puts the GlitchCatcher™ mosfets on the correct side of the VRM connector, in order to reduce stray inductance.
