EVM User's Guide: LM5185EVM-SIO
LM5185-Q1 Single-Isolated-Output Evaluation Module
Description
The LM5185-Q1 controller uses an external power
MOSFET and has adjustable loop compensation and
current limit. All these features bring flexibility and
design optimization for power scaling, transformer
design, and BOM optimization, as well as
overall performance and solution cost. Other user
programmabilities are also supported including
the input UVLO with hysteresis, soft-start, and
temperature compensation.
Get Started
1. Order the EVM at ti.com.
2. Read this user's guide carefully.
3. Prepare the bench setup per instructions. Take
cautions to prevent damage by ESD when
handling the EVM.
4. Power up the EVM by following the recommended
steps.
5. Run tests and measurements. Take cautions of
high voltage and hot temperature produced by the
EVM during test.

Features
• Wide input voltage range (default 20V to 60V,
extendable 6V to 90V)
• Tight voltage regulation of the isolated output
without opto-coupler: 16.4V ±1.5%
• Removal of the opto-coupler and transformer aux
winding saves solution size and cost.
• Peak conversion efficiency > 90%
• Programmable loop compensation, current limit,
input UVLO, and thermal compensation allowing
for flexible and optimal designs.
Applications
