This document authorizes the release of the updated schematic diagram for the ILPI354 Voltage Amplifier (VA) module. This update supersedes the previous revision [Insert Old Rev] and incorporates necessary design modifications to enhance signal integrity and thermal performance.

The ILPI354 is a manufactured by brands like ILP (International Lightning Products) and found in generic Chinese power supply modules. It is functionally similar to the ubiquitous UC3842/3843 series but with optimized internal compensation and lower startup current.
