TPS92515HVEVM-749 High Current Buck LED Driver Evaluation Module
1
Introduction
The TPS92515HVEVM-749 evaluation module (EVM) helps designers evaluate the operation and
performance of the TPS92515 buck switching regulator designed for high-current LED drive applications.
The TPS92515 is designed to control the drive of high-brightness light-emitting diodes (LED) and features
a wide input voltage range (5.5 V to 65 V), PWM dimming capability, analog dimming capability, and input
undervoltage protection.

Warnings and Cautions
Observe the following precautions when using the TPS92515HVEVM-749.
CAUTION:
Caution! Do not leave EVM powered when unattended.
HOT SURFACE:
Caution Hot Surface! Contact may cause burns. Do not touch. Please take the proper
precautions when operating.
HIGH VOLTAGE:
Danger High Voltage! Electric shock possible when connecting board to live wire. Board should
be handled with care by a professional. For safety, use of isolated test equipment with
overvoltage/overcurrent protection is highly recommended.
WARNING
When choosing your LED component (not included
with this EVM) the end user must consult the LED data sheet
supplied by the LED manufacturer to identify the EN62471 Risk
Group Rating and review any potential eye hazards associated with
the LED chosen. Always consider and implement the use of
effective light filtering and darkening protective eyewear and be
fully aware of surrounding laboratory-type set-ups when viewing
intense light sources that may be required to minimize or eliminate
such risks in order to avoid accidents related to temporary
blindness.
