Setup
This section describes the jumpers and connectors on the EVM as well as how to properly connect, set
up, and use the LM36010EVM.
1.1
Input/Output Connector Description
VINL, GND (Banana Connectors) –
These are the power input terminals for the driver and provide a
power (VINL) and ground (GND) connection to allow the user to attach the EVM to a cable harness.
TP1 (Test Point) –
This pin can be used to measure the input voltage VIN.
VINL, VIN (Jumper J2) –
The user can monitor the inductor current and input current waveforms by
omitting this jumper and using separate wires from the power supply to the VINL and VIN pins. This will
remove the input capacitors from the inductor and eliminate their filtering effect to the inductor current.
STROBE (Jumper J3) –
STROBE is an active high hardware flash enable. This pin can be used to
monitor the STROBE signal.
PWM, STROBE, GND (Jumper J4) –
This jumper provides an external method for initiating a flash event.
The STROBE pin is connected to ground via a 300-k
Ω
resistor internal to the LM36010EVM. To externally
drive this pin, either connect a control signal directly to the STROBE pin of the connector or place a
jumper between the pins STROBE (J4<2>) and PWM (J4<1>). PWM can be configured as a time-
adjustable voltage pulse via the General User Interface (GUI) software provided or can be driven
externally using a function generator.

VOUT (Jumper J5) –
This pin can be used to measure the output voltage.
VOUT, VLED (Jumper J6) –
This jumper provides access to the regulated output of the driver and the
output of the LED current sources. The user can measure VOUT with reference to GND, VLED with
reference to GND, and current source headroom directly between VOUT and VLED.
GND (Jumpers J8, J9, and J10) –
These are additional pins to connect to ground (GND).
VLED, D1A (Jumper J11) –
Connect VLED (J11<1>) and D1A (J11<2>) to light the LED as it connects
the LED output of the driver to the on-board anode of the flash LED.
VIO (Jumper J12) –
This pin can be used to measure the VIO.
3.3V, VIO, VIN (Jumper J13) –
This jumper provides pullup for the I
2
C lines (clock and data). VIO
(J13<2>) can be connected to the 3.3-V pin (J13<1>) of the TI LaunchPad™. Communication via the I
2
C
interface may not be possible if the supply voltage to the LED driver is below approximately 3 V.
