LM36010EVM User Guide
The input voltage range for the flash driver is 2.5 V to 5.5 V. The on-board LED or an LED module should
be connected for proper operation.
The LM36010EVM dissipates power, especially during high current and long duration flash events. Power
will also be dissipated on the flash LEDs. TI recommends that in order to prevent overheating, repeated
flash events in very short time intervals is avoided. Special care must be taken with regards to thermal
management when using time-out values greater than 500 ms.
The EVM layout is designed to minimize temperature rise during operation. Depending on the PCB layout,
input voltage, and output current, it is possible to have the internal thermal shutdown circuit trip prior to
reaching the desired flash time-out value. A warning is also placed on the EVM as a safety measure.

For proper operation of the LM36010EVM, the jumpers should be properly configured. The recommended
setting using shorting blocks is:
•
VIO (J13<2>) to 3.3 V (J13<1>) if TI Launchpad is used
•
STROBE (J4<2>) to PWM (J4<1>) or external signal
•
VLED (J11<1>) to D1A (J11<2>)
Texas Instruments has created LaunchPad (MSP432) and an I
2
C-compatible graphical user interface
(GUI) that can help exercise the part in a simple way. A description of how to install and use the
LaunchPad and the GUI is contained in
and
.
The LM36010EVM has the means to “plug into” the LaunchPad BoosterPack connectors, which provide
the control signals for the simple interface. Power to the part needs to be provided externally. A USB
cable provided in LaunchPad MSP432 kit should be connected to the LaunchPad board from a PC as
shown in
.
