TPS40140EVM-002: 1.5V and 3.3V @ 20A, 12V in

Summary

TPS40140EVM-002 is designed to use a regulated 10.8V to 13.2V bus to produce two high-current, regulated outputs. Both outputs are capable of supplying up to 20A of load current.

The TPS40140EVM-002 is design to demonstrate the TPS40140 in a typical regulated bus to low-voltage application while providing a number of test points to evaluate the performance of the TPS40140 in a given application.

Features:

  • 10.8V - 13.2V input range

  • 3.3V and 1.5V fixed output

  • 20A DC steady-state current per output

  • 500kHz switching frequency per phase

  • Single main switch N-channel MOSFET and two synchronous rectifier N-channel MOSFETs per phase

  • Convenient test points for probing critical waveforms and non-invasive loop response testing
