1 Description

The TPS51219EVM evaluation module (EVM) is designed to use a regulated voltage ranging 8 V to 20 V to produce 1.05-V output at up to 20 A of load current. The TPS51219EVM demonstrates the TPS51219 in a typical low-voltage application with D-CAP2™ mode operation. The EVM also provides test points to evaluate the performance of the TPS51219.

1.1 Typical Applications

  • Notebook computers
  • I/O supplies
  • System power supplies

1.2 Features

The TPS51219EVM features:

  • D-CAP2™-mode operation with low-ESR output capacitance
  • 2% tolerance 1.05-V output voltage
  • 20-Adc, steady-state output current
  • Support prebias output voltage start-up
  • 500-kHz switching frequency
  • SW1 for enable function
  • Convenient test points for probing critical waveforms
