IMPORTANT NOTICE:
Please read this document before setting up a VTM evaluation board
This user guide is not comprehensive and the operator should not substitute it for
common sense and good practice. The following procedures should be followed
during operation:
Wear approved safety glasses when testing electronic product.
n
Provide strain relief for wires and secure the board on the test bench to avoid
n
displacement.
Remove the power and use caution when connecting and disconnecting all test
n
probes and interface lines to avoid unintentional short circuits and contact
with hot surfaces.
Never attempt to disconnect the evaluation board from a PRM® evaluation board
n
while power is applied. This system is not designed to demonstrate the
hot plug capability.

    General Components 1. VTM® (PS10) 2. Input lugs (+IN and –IN): Sized for #10 hardware. Use these for making connection to the input source. This board does not contain reverse polarity protection. Check for proper polarity before applying power. 3. Input filtering: Input capacitor (CIN) and filtering (ceramic capacitors) allows for stable operation with most input sources.
  • Page 5: Test Points And Sockets Description

    Test Points and Sockets Description Each test point socket accepts 0.015 – 0.025 inch diameter leads of solid wires and through-hole components for use with external circuitry and test equipment. All test points are aligned on the board’s edge for easy access, measurement and external circuitry connections.

  • Page 12: Standalone Operation Vs Prm-Vtm Operation

    & VTM Evaluation Boards ® ® The VTM evaluation board has been designed for compatibility with all PRM evaluation boards to accommodate any PRM-VTM combination. The VTM evaluation board contains dual connectors designed to mate with J10 and J13 on PRM board. An additional signal connector shares VTM signal pins along with TM, S+ and S- to the PRM board.
  • Page 13: Push Pin Heat Sink Installation

    Paralleling The paralleling and current sharing capability of the devices can be demonstrated by stacking multiple evaluation boards and interconnecting the inputs and outputs with standoffs of sufficient current rating to create a parallel array. When paralleling VTMs, in standalone VTM® operation, VC pins should be connected together to enable the synchronized startup.
