The Texas Instruments LM76005QEVM evaluation modules (EVM) help designers evaluate the operation and performance of the LM76005-Q1 wide-input voltage buck regulator. The output voltage for the device offers configurability from 1-V to 95% of V_IN, synchronous rectification, PFM, and forced PWM mode and a 200-kHz to 500-kHz adjustable frequency range with a 400-kHz default frequency. It also offers external frequency synchronization, power-good (PG) flag, and a precision enable to program undervoltage lockout (UVLO) and internal compensation. Built-in protection includes current limit, overvoltage and undervoltage protection, and thermal shutdown. The LM76005QEVM is configured for an output voltage of 3.3 V and a switching frequency of 400 kHz. Refer to the LM76005-Q1 3.5-V to 60-V, 5-A Synchronous Step-Down Voltage Regulator Data Sheet for additional features, detailed description, and available options.

The EVM contains one DC-DC converter (see Table 1-1).

This section describes the test points and connectors on the EVM and how to properly connect, set up, and use the LM76005QEVM. Refer to Figure 2-1 for a top view of the EVM and relative placement of the different test points and connectors.
