This document is the demo manual for DC2230A-A, which introduces the features and characteristics of the product
This document provides instructions for evaluating the LTM4636EY 40A DC/DC µModule regulator in the DC2230A-A demonstration circuit. It includes a quick start procedure, performance specifications, parts list, and schematic diagrams. The circuit supports input voltages from 4.7V to 15V and output voltages from 0.6V to 3.3V. It operates in continuous conduction mode under heavy load and offers options for pulse-skipping or Burst Mode for noise-sensitive applications. The manual also details component values, jumper configurations, and measurement setups for testing efficiency, load transient response, and thermal performance.
