LM76002EVM-500K: 3.3V @ 2.5A, 3.5 ~ 60V in, Buck Converter

Summary

The LM76002EVM-500K evaluation module (EVM) is a fully assembled and tested circuit for evaluating the LM76002 synchronous step-down converter. The EVM operates from an 3.5V to 60V input and provides a 3.3V or 5V output at 2.5A.

The Texas Instruments LM76002EVM-500K evaluation modules (EVM) help designers evaluate the operation and performance of the LM76002 wide-input voltage buck regulator. The output voltage for the device offers configurability from 1-V to 95% of VIN, synchronous rectification, PFM, and forced PWM mode and a 300-kHz to 2.2-MHz adjustable frequency range with a 500-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 LM76002 EVM is configured for an output voltage of 3.3 V or 5 V and a switching frequency of 500 kHz. Refer to the LM7600x data sheet for additional features, detailed description, and available options.
