LM46001PWPEVM: 3.3V @ 1A, 3.5 ~ 60 Vin

Summary

The Texas Instruments LM46001EVM evaluation module (EVM) helps designers evaluate the operation and performance of the LM46001 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 aprecision enable to program undervoltage lockout (UVLO) and internal compensation.

The LM46001EVM is configured for an output voltage of 3.3 V and a switching frequency of 500 kHz. Refer to the LM46001 datasheet for additional features, detailed description and available options.
