| FAN5617 TinyWireTM Single-Wire Control Evaluation Kit December 2006 FAN5617 High Efficiency, Constant-Current LED Driver with Adaptive Charge Pump and TinyWireTM Single-Wire Control Evaluation Kit 3-Channel Parallel LED Driver with TinyWireTM Digital Brightness Control 32 Static Brightness Levels with 5-Bit Internal DAC Built-in Charge Pump with Three Modes of Operation 1x Linear , 1.5x and 2x Up to 90% Efficiency Low EMI, Low Ripple 2.7V to 5.5V Input Voltage Range 1MHz Operating Frequency 3x3mm 16-Lead MLP Package Figure 1 FAN5617MPX Evaluation Board The FAN5617 Evaluation Board is a compact circuit including the FAN5617 in a 3x3mm 16-pin MLP package. LED brightness is controlled via a simple one-wire digital interface. The evaluation board includes a USB interface with mini-B receptacle for easy connection to a PC. A "dashboard" program is provided on an installation CD to set the LED brightness using the TinyWireTM interface. The FAN5617 evaluation board, a completely assembled and tested surface mount board, provides easy probe access points to all inputs and outputs so that electrical characteristics and waveforms can be easily measured. Kit Contents FAN5617 Evaluation Board USB Type A to Mini-B Data Cable Software Installation CD PC System Requirements A PC or Laptop running Windows 2000 or Windows XP with an available USB port connection. USB is required for the FAN5617 to run from USB-power. USB may be used with an external power supply to run the FAN5617 see Power Options on next page . Set-up and Installation Procedure Insert the CD-ROM. If the installation program does not run automatically, run Setup.exe, which is in the root directory of the CD-ROM. If you choose to run the program after installation, and before completing step #2 below, you will get an error message. Connect the USB cable between the eval board and PC. Windows should then find the device and attempt to install the driver. Connect any external power supplies, if desired. The FAN5617 eval board can be powered from the USB cable if USB is used. Run the software “FAN5617 TinyWire Control Panel" FAN5617 TinyWireTM Single-Wire Control Evaluation Kit Power Options To Power the FAN5617 from the USB bus Connect jumper J1 pins 1 and This is the default configuration when the eval board is shipped. To use External Power for the FAN5617 Open jumper J1 pins 1 and Connect power supply + - 5.5V to TP6 and power supply - to TP3. Measurement Options Test Point/Jumper TP1 DATA TP2 EN TP3, TP7 GND TP4 VOUT TP6 VIN J2 - J4 Measurement Description Monitor DATA or Monitor the DATA line via TP1. Or apply external DATA signal to TP1 and either remove Apply External DATA jumper J6 or check the "Tri-State Data" Box pictured in Figure 4 to over ride USB chip. Monitor ENABLE or Apply External ENABLE Monitor the EN line via TP2. Or apply external ENABLE signal to TP2. Ground Test Point. Output Voltage Apply volt-meter at TP4 to measure output voltage. Supply Current Apply ammeter between the external power supply V+ output and TP6 Remove Jumper J6 to see only the FAN5617 supply current without including the current consumed by the USB chip IO. Output LED Current Apply ammeter to pins 1 and 2 of jumper J2, J3 or J4. Figure 2 Test Point and Jumper Summary VCC R4 470 C5 0.1uF |
