This user's guide describes the characteristics, operation, and use of the UCC27735-Q1 Evaluation Module (EVM). A complete schematic diagram, PCB layouts, and BOM are included in this document.
The EVM is developed in such a way that the UCC27735-Q1 driver performance can be evaluated and compared to data sheet parameters, or externally connected to power devices with provisions for source and sink gate-resistance flexibility. The UCC27735Q1EVM evaluation board uses surface-mount test points allowing connection to LI, HI, VDD, and HB inputs. A variety of other test points are available for probing the UCC27735-Q1. The input bias is configured such that the VHB-VHS high-side bias can be sourced from VCC, or an external additional bias can be added to provide VHB-VHS directly. The high- and low-side driver output returns are separated on HS and GND respectively to allow evaluation of the UCC27735-Q1 HS negative voltage capabilities. For detailed device information, see UCC2773x Data Sheet and UCC2773x-Q1 Data Sheet.
