LM46002PWPEVM: 3.3V @ 2A, 3.5 ~ 60V in, Buck

Summary

The Texas Instruments LM46002EVM evaluation module (EVM) helps designers evaluate the operation and performance of the LM46002 wide-input voltage Simple Switcher® buck regulator. The device offers configurability in a 1-V to 28-V output voltage, synchronous rectification and a 200-kHz to 2.2-MHz adjustable frequency range. It also offers external frequency synchronization, power good (PG) flag, and a precision enable to program undervoltage lockout (UVLO) and internal compensation.

The LM46002EVM is configured for an output voltage of 3.3 V and a switching frequency of 500 kHz.

Refer to the LM46002 datasheet for additional features, detailed description and available options.
