Page 3: Introduction
Isolated DC-DC Converter capable of delivering up to 2-W of power. Since the UCC14240-Q1 provides isolated power in an integrated package, this allows systems to reduce cost and size by removing the need for separate isolated power supplies. The UCC14240-Q1 delivers class-leading efficiency in power conversion from the primary to the secondary side while removing the need for bulky external transformers or power modules commonly used in existing designs. -

Page 5: Description
The EVM allows users to test functions of the UCC14240-Q1 such as: Enable/Disable (EN) of the device as well as configure the isolated output voltage for 15 V<VDD<20 V, and -5 V<VEE<0 V and easily apply variable loads to the outputs. This EVM allows the user to measure efficiency across the input voltage range and varying output loads according to system requirements. -

3-1, TP4 (COM) is the midpoint of a capacitive divider and is intended to connect to the COM pin of the isolated gate driver IC. When the UCC14240-Q1 is used to bias a gate driver IC, VDD (VDD-COM) and VEE (VEE-COM) are referred to with respect to COM. In this case consider COM as a virtual GND to the gate driver IC. -
