Always use electrical safety precautions to help ensure the user's personal safety and the safety of those working around the user. Contact TI’s Product Information Center TI's Product Information Center for further information. Save all warnings and instructions for future reference. Failure to follow warnings and instructions can result in personal injury, property damage, or death due to electrical shock, burn hazards, or both. The term TI HV EVM refers to an electronic device typically provided as an open-framed, unenclosed printedcircuit board assembly. It is intended strictly for use in development laboratory environments, solely for qualified professional users that have training, expertise, and knowledge of electrical safety risks in development and application of high-voltage electrical circuits. Any other use, application, or both, are strictly prohibited by Texas Instruments. If the user is not suitably qualified, the user should immediately stop from further use of the HV EVM. • • Work Area Safety: – Maintain a clean and orderly work area. – Qualified observer or observers must be present any time circuits are energized. – Effective barriers and signage must be present in the area where the TI HV EVM and its interface electronics are energized, indicating operation of accessible high voltages can be present, for the purpose of protecting inadvertent access. – All interface circuits, power supplies, evaluation modules, instruments, meters, scopes, and other related apparatus used in a development environment exceeding 50-VRMS/75-VDC must be electrically located within a protected Emergency Power Off (EPO) protected power strip. – Use a stable and non-conductive work surface. – Use adequately insulated clamps and wires to attach measurement probes and instruments. No freehand testing whenever possible. Electrical Safety: As a precautionary measure, it is always a good engineering practice to assume that the entire EVM may have fully accessible and active high voltages. – De-energize the TI HV EVM and all its inputs, outputs, and electrical loads before performing any electrical or other diagnostic measurements. Confirm that TI HV EVM power has been safely deenergized. – With the EVM confirmed de-energized, proceed with required electrical circuit configurations, wiring, measurement equipment hook-ups, and other application needs, while still assuming the EVM circuit and measuring instruments are electrically live. – When EVM readiness is complete, energize the EVM as intended. WARNING WARNING: While the EVM is energized, never touch the EVM or its electrical circuits as they could be at high voltages capable of causing electrical shock hazard. 2 LMR38020EVM User Guide SNVU787A – JULY 2021 – REVISED SEPTEMBER 2022 Submit Document Feedback Copyright © 2022 Texas Instruments Incorporated www.ti.com • • General TI High Voltage Evaluation User Safety Guidelines Personal Safety: – Wear personal protective equipment, for example, latex gloves, safety glasses with side shields, or both, or protect the EVM in an adequate lucent plastic box with interlocks from accidental touch.

See Figure 2-1 for a top view of the EVM. VOUT (J2) Output voltage of the converter VOUT connector and test point connected to the power inductor and the output capacitors. Connect the loading device between VOUT and GND connectors to provide loading to the regulator. Connect the loading device to the board with short wires to handle the DC output current. GND Ground of the converter GND is connected to the LMR38020 GND as well as the return terminals of the input and output capacitors. GND is the current return path for both supply voltage and load. Connect to supply and load grounds with short wires. VIN (J3) Input voltage to the converter VIN connector and test point connects to the input capacitors and the VIN pin of the LMR38020. Connect the supply voltage from a power supply or a battery between the VIN and GND connectors. The voltage range must be higher than 4.2 V for the device to be active. VVIN higher than 6 V provides a regulated 5-V output voltage. To avoid damaging the device, VVIN must be no greater than 80 V. The current limit on the supply must be high enough to provide the needed supply current when the output is fully loaded. The supply voltage must be connected to the board with short wires. VIN_EMI Input voltage to input filter of the converter If an input filter is desired between the supply voltage and the LMR38020, connect the supply voltage between VIN_EMI and GND on the bottom layer. The supply voltage must be connected to the board with short wires. The EMI filter components were not assembled on this evaluation board. VIN_S(TP1) Measure VIN voltage It provides a direct connection to the input capacitor C10 to sense the input voltage. Do not apply input voltage on this test pin. SYNC (J5) SYNC clock injection J5 is used to synchronize the switching frequency to external clock. Refer to the LMR38020 SIMPLE SWITCHER® 4.2-V to 80-V, 2-A Synchronous Buck Converter Data Sheet for detail application information. Do not short J5 SYNC pin to ground.
