UCD91320EVM

Overview

The UCD91320EVM development kit is an easy-to-use evaluation module (EVM) for the UCD91320 Power Sequencer device. The EVM includes everything needed to start developing power sequencer solutions alongside the TI Sequencer Studio GUI. This EVM features the UCD91320, as well as 4 on board LDOs to quickly get started sequencing multiple power rails. The EVM also features LEDs to view signal states, footprints for RC filters for margining and for power rail monitoring. Communication with the EVM is easily accomplished using PMBus.

Features
  • UCD91320SPM device mounted on board
  • USB power supply connector
  • Easy to access pin headers for every signal on the board
  • 4x LDOs for quickly prototyping various power rails: 3.3V, 2.5V, 1.8V, and 1.2V.
  • Jumpers to easily enable or disable each on board LDO
  • RC filters for margining feedback, footprints for additional passive elements, jumpers to connect the LDO output to the monitoring pins and to off board devices as well.
  • Pin header for PMBus connections
  • Easy to use jumpers for PMBus address selection, with up 8 selectable addresses
  • On-board LDO to power UCD91320
  • Test points for checking the voltage reference, power supply pins, and external power supply monitoring
