Introduction
The LM3559/LM3560 Evaluation Board is designed to fully evaluate the LM3559 and LM3560
Synchronous Boost Converter with dual 900mA High Side Flash LED Drivers (LM3559) or dual 1000mA
High Side Flash Drivers (LM3560) and I2C-Compatible Interface. Detailed descriptions for either parts can
be found in their device-specific data sheets.

The board comes equipped with two Lumiled Flash LEDs (LXCL-EYW4). An additional LED (LED3) is a
red LED which operates as the message indicator. The on-board flash button demonstrates the hardware
flash feature of the LM3559/LM3560 and, when pushed, the Flash LEDs turn on at their programmed
Flash current. There are two 4.7kΩ pull-up resistors on board for the I2C clock and data lines and a 4.7kΩ
pull-up (R_HWEN) that pulls the active high hardware enable pin (HWEN) high. Each Input and/or output
from the LM3559 has its own separate header pin to serve as a test-point.

USB Interface Board Connector
Operation
To operate the LM3559/LM3560 evaluation board, connect a jumper from the VI/O pin to the IN pin (3-pin
header at bottom left of board). This connects the logic level pull-ups to VIN. Next, connect a jumper
across the IN VL header. This will short the IN pin and the input terminal of the inductor. This jumper is
designed to remove the input bypass capacitor from the input of the inductor to measure the inductor
current ripple. With these jumpers in place, connect a 2.5V to 5V supply between the VL banana jack and
GND.
Control of the LM3559/LM3560 can be done via two ways. At the top left corner of the board there are two
2-pin headers (SCL/GND and SDA/GND). To control the LM3559/LM3560 using a data generator or an
external I2C device connect the I2C lines directly to the SCL and SDA pins of the respective header.
Alternatively you can use the Texas Instruments USB board to supply the I2C data (see Section 3.1).
3.1
Operation With Texas Instruments USB Interface
The USBL and USBR connectors (16 pin connectors mounted on the bottom of the board) plug directly
into the Texas Instruments USB Interface Board. The connectors are keyed so the boards will fit together
only one way. The 3-position header at the bottom of the board (VUSB VI/O VIN) connects the evaluation
boards pull-up resistors, tied to VI/O, to either VIN or to the 3.3V regulator (VUSB) from the USB board.
Connecting a jumper across VIN/VUSB at the top right of the board allows for power (at the VL pin) to
come from the USB Interface Board. This is useful for demonstrating the device without an external power
supply. Keep in mind that the USB board has a 500 mA current limit and is either 3V or 5V depending on
the (J1) jumper setting on the USB Interface Board (for details, see the USB Interface Module for
Applications document). High-current requirements such as high Flash mode and higher Torch mode
currents will require an external supply at VL. Also ensure the VIN/VUSB jumper is left open when
connecting an external supply to the VL plugs as this will cause a conflict with the power supply from the
Interface Board and the external supply connected to VL.
After power is applied to the LM3559/LM3560 Evaluation Board, connect the USB Interface Board to a PC
with the LM3559.exe or LM3560.exe program installed. The LM3559.exe and LM3560.exe programs are
simple executables that can be copied to a folder on the PC. (see Figure 2 and Figure 3).

3.2
LM3559 Graphical User Interface
The LM3559 graphical user interface features all the register options that are programmable within the
LM3559. When the LM3559.exe program is executed and any button is pressed or drop down box is
selected, the program will automatically update the LM3559 with the settings of the appropriate register.
When starting up the LM3559.exe program the screen displays the default (power on/reset) settings of the
device. The Default button in the program will write all the LM3559 registers to their default state and
populate the LM3559.exe with the default information.
3.3
LM3560 Graphical User Interface
The LM3560 graphical user interface operates similar to the LM3559. The differences are: bit 2 in the
Enable Register (0x10) in the LM3560.exe has the option for 2 levels of Privacy Mode Current, the Torch
and Flash Current nominal settings are different, the LM3560.exe 's Configuration Register 2 (0xF0)
reflects the additional option for a TX1 Shutdown, and the VLED Monitor Register nominal thresholds are
different between devices.
The Following sections detail each different field within the LM3559.exe/LM3560.exe program.
3.4
Simple I2C Interface
The top three fields (I2C Address, Address, and Data) provide for a simple way of writing directly to the
registers of the LM3559/LM3560. The I2C Address field shows the I2C slave address (0x53). The I2C (hex)
address is written into the Address field and the I2C (hex) data is written in the Data field. The Write
Button will write the contents to the LM3559/LM3560 and the Read button reads back the (hex) data.

3.18 General-Purpose Input/Output (GPIO) Register
The GPIO Register field contains the buttons and drop-down menus to configure the GPIO Register. The
GPIO1 Control and GPIO2 Control provide the drop-down menus for setting the particular pin as either an
input or an output. The GPIO1 Data and GPIO2 Data display the data (GPIO Output) or will read back the
data (GPIO Input) that is entered in the respective field. When configuring the GPIO’s as outputs, a double
write is required to the GPIO register. For example, if both GPIO’s are inputs, in order to make both GPIO
outputs, two writes of b00X11X11 to the GPIO register are required. (X represents the output data). The
drop-down menus which contain the GPIO write commands take this into account, so when the LM3559 or
LM3560's Graphical User Interface program is used, the double write process is not required.

When configured as inputs, in order to read back a change of data on the GPIO input, the particular GPIO
pin must be reconfigured as an input (Write) and then the data on the pin can be read back (Read). For
example, if both GPIO pins are inputs and the previous data on the pin was a logic ‘1’, but then changed
to a logic ‘0’, in order to read the logic ‘0’ into the GPIO register the read sequence would first be a Write
of (b00X01X01) to register 0x20, then a Read of register 0x20 would be done to read in the new data. The
GPIO Read button is available to read back the contents of the GPIO Data fields (GPIO Inputs Only). This
button takes into account the Write /Read (2 instruction process) so only a push of the Read button is
required to read in the contents of the GPIO lines.
The Interrupt Enable button controls the interrupt option available for GPIO2.
