LM43603PWPEVM: 3.3V @ 3A, 3.5 ~ 36V in, Buck

Summary

The Texas Instruments LM43603EVM evaluation module (EVM) helps designers evaluate the operation and performance of the LM43603 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 LM43603EVM is configured for an output voltage of 3.3 V and a switching frequency of 500 kHz.

Refer to the LM43603 datasheet for additional features, detailed description and available options.
