3.1 Evaluation Setup

This section describes the default EVM configurations and recommended test set up for the UCC21551-Q1 EVM.

Equipment

The following equipment is recommended for testing the EVM:

  • One DC supply capable of 5 V/0.5A, for example: Keysight E3634A.
  • One DC supply capable of 24 V/0.5A, for example: Keysight E3634A.
  • One Arbitrary Function Generator, dual channel, for example: Tektronix AFG3102A
  • One Oscilloscope, at least 3 channels, bandwidth 200 MHz or above, for example, Tektronix MDO3054 or TDS3054C.
  • Three passive oscilloscope probes, bandwidth 200 MHz or above. For example, TPP1000 like probe with a ground spring.
  • 4X BNC to Grabber Cables for input and supply connections.
  • Banana plug connector.

Equipment Configurations

  • DC Power Supply Settings
    • DC Supply 1:
      • Voltage setting: 5 V
      • Current limit: 0.5A
    • DC Supply 2:
      • Voltage setting: 24 V
      • Current limit: 0.5A
  • Function Generator Settings
    • Function: Pulse
    • CH1: High: 5 V, Low: 0 V
    • CH2: High: 5 V, Low: 0 V
  • Oscilloscope Settings
    • CH1-CH3:
      • DC coupling
      • Highest bandwidth setting available
      • Termination 1M or automatic
      • Probe scale: 10X or auto

Equipment Setup

  • Jumper Connections
    • J7: Shunt XEN to VCC
    • J20: Shunt ON to EN
    • J5: Shunt DT to GND
    • SDT_DT1: All switches in the left most position
  • Oscilloscope Connections
    • CH1: VGA to VSSA
    • CH2: VGB to VSSB
    • CH3: VDDB to VSSB
  • Function Generator
    • CH1: INB to GND
    • CH2: INA to GND
  • Power Supply
    • DC Supply 1: J18
    • DC Supply 2: J21

If testing the EVM with FETs, then populate Q1 and Q2 or the XM3 connector. If testing the EVM without FETs, then place a banana plug connector between SW and DC-. See Figure 4-1 for a visual of the default test connections.
