SLVUC72C October 2021 – November 2022 TPSI3050-Q1
TPSI3050Q1EVM EVM (Evaluation Module) helps designers evaluate the operation and performance of the isolated switch driver, TPSI3050-Q1. This user's guide provides the connectors, test point descriptions, operational modes, schematic, bill of materials, and board layout of the EVM. The TPSI3050-Q1 is a 5-kVRMS reinforced isolated switch driver with 1.5-A peak source current and 3-A peak sink current. The device is able to generate a regulated secondary power supply of 10 V. This regulated power supply allows for a wide selection of MOSFETs or SCRs. The EVM includes two back-to-back 650-V and 42-A NMOS with D2PAK package for easy testing and footprint for one SCR with a TO247-3 package. The inputs and outputs connections to the board are terminal blocks, which allow for easy wired connections. The EVM is rated for a load up to 500-VDC/350-VRMS and 4 A. The board contains multiple test points to monitor the TPSI3050-Q1 functionality. In addition, the EVM contains a 3.3-V LDO to supply VDDP from a battery to the input of the TPSI3050-Q1 with an output of 3.3 V. The EVM allows the user to test multiple applications, such as AC/DC Solid State Relay (SSR), battery management, and precharge circuits.
