Introduction - Texas Instruments MLTLDO2EVM-037 User Manual

Introduction

3. Personal Safety
a. Wear personal protective equipment (for example, latex gloves or safety glasses with side shields)
or protect EVM in an adequate lucent plastic box with interlocks to protect from accidental touch.
Limitation for safe use:
EVMs are not to be used as all or part of a production unit.
2 Introduction
TI's MLTLDO2EVM-037 helps design engineers evaluate the operation and performance of linear
regulators for possible use in their own circuit application. The MLTLDO2EVM-037 EVM offers four linear
regulator designs, each one electrically isolated from the other through tab routing in the PCB fabrication
step. The boards can be quickly separated through the breakaway tabs if desired. Combined, the boards
can mount many linear regulators which come in the DDA, DCY, 3-pin KVU and 5-pin KVU packages. The
boards that carry the DDA, DCY and 3-pin KVU packages have been designed to withstand up to 100 Vdc
of voltage across its input and output terminals. The board carrying the 5-pin KVU package has been
designed to withstand up to 50 Vdc of voltage across its input and output terminals. All four boards have
been designed to withstand 5 Adc of current draw. This allows the EVM to be used for numerous linear
regulator designs in TI's portfolio, as well as future designs that may operate into high voltage or high
current. Each board is designed to populate multiple input and output capacitors, allowing the user to
customize the EVM for their specific needs. User-selectable grounding is available on each board,
allowing the user to evaluate the linear regulator in a floating application. Thermal vias have been placed
near each linear regulator to aid in thermal spreading of the heat generated by the device. The EVM
comes with four bumpons to lift the EVM off of the test surface, and mounting holes are provided for
standoffs or mounting to an external chassis. Additional features provided for each design are covered in
this User's Guide.
2.1 Before You Begin
The following warnings and cautions are noted for the safety of anyone using or working close to the
MLTLDO2EVM-037. Observe all safety precautions.
Danger: HIGH VOLTAGE! This evaluation board is intended for
professional use only. This board has exposed high voltages. Do
not operate this board without proper high-voltage and high-
current safety practices. Read this user guide carefully before
testing with the MLTLDO2EVM-037. Use floating measurement
equipment such as high-voltage differential scope probes.
Hot surface. Contact may cause burns. Do not touch.
The circuit module can be damaged by overtemperature. To avoid damage,
monitor the temperature during evaluation and provide cooling, as needed, for
your system environment.
