2 Description

The UCC14240EVM-052 is intended to allow designers to evaluate the performance characteristics and capabilities of the UCC14240-Q1 quickly and easily for use in automotive, isolated, gate driver bias applications as well as a variety of isolated industrial bias power applications. 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. Another feature of the EVM is the ease of probing during test. Test points, are strategically placed and described according to Table 4-1.
