Note 3 : using X5R type ceramic capacitor is preferred. Using X7R brings extended operating temperature range. Using Y5R material shall be avoided due to the wide tolerance spread over the temperature range. Using smaller foot print capacitor is discouraged to avoid audible noise issue with the ceramic. ASSEMBLY Note : the here attached photos are used as a visual reference. 1234- Assemble the NCP5623B (LLGA12 package ) , Hot Air Flow Process recommended Assemble all the passive parts Assemble all the White LED Assemble the power supply pins. At this point, the system is ready to operate. Page 4 / 13 MB-MAY-18th 2009 5/19/2009 NCP5623C-DEMO-V7 ON Semiconductor NCP5623C DEMO BOARD BOM – V7.0 TEST CONDITIONS Power Supply : The system can be powered either by the USB port ( assuming the board is attached to the MCU board using the J1 connector )or by a standard DC power supply. In any case, one single source of power shall be connected : either the USB or the power supply, but not simultaneously. If a DC power supply is used, make sure it can supply 500mA continuous output current across the two pins built with connector J2. Make sure the polarity is properly respected : although a built-in zener prevent for such failure, reverse polarity might destroy the board. Set up the power supply to any value between 3.2 V minimum to 5.0V maximum. Typically, the supply voltage shall be adjusted between 3.2V – 4.2V to emulate standard Li-Ion battery. The NCP5623B being controlled through the I2C port only, an external controller must be provided to send the appropriate commands to the chip. One can select either of the possible digital sources: - use an external I2C generator to send the command - use the MCU board available from ON Semiconductor ( P/N = JB16) Manufacturing Final Test : 1 - Double check the power supply is set up at 3.6V, maximum rating is 5.0V. 2 – Download the NCP5623B/T demo software into the MCU flash memory. Use the P&E standard hardware and software tools. 3 – Download the GUI program and run it 4 – Turn ON the power supply : the input current shall be in the 4mA to 10mA range, no LED shall be ON. Reset the MCU if necessary by pushing the RESET button S7 5– Attach the USB connector to the USB port of the external computer. The “USB OPEN” message should be displayed on the bottom, left hand side of the window. 6– Use the slider, located on the left side of the GUI, to increase/decrease the ILED current: the chip is considered PASS if the brightness of the three LED varies accordingly to the position of the slider. 7 – Set the ILED current to zero 8– Disconnect the USB port 9- Turn off the power supply to complete the sequence. At this point, the final test is completed and considered PASS if all the LED have been properly activated. Digital Control : it is possible to drive the NCP5623T demo board with an ON Semiconductor MCU board and a Window TM based software dedicated to the chip. To operate such mode of operation, the board shall be connected to the USB port of the host PC with a standard mini USB connector attached to the MCU board USB port.

Note : the charge pump function is NOT implemented in the NCP5623T version. Page 7 / 13 MB-MAY-18th 2009 5/19/2009 NCP5623C-DEMO-V7 ON Semiconductor NCP5623C DEMO BOARD BOM – V7.0 MANUAL LED BRIGHTNESS CONTROL - set each PWM at the appropriate percentage. Any PWM loaded with zero will switch OFF the associated LED set the ILED maximum current with the ILED slider : the DC current flowing through each LED will increase/decrease accordingly, the brightness being a function of the associated PWM per LED. AUTOMATIC GRADUAL DIMMING Gradual Dimming UP - In order to visualize the effect, make sure to set the ILED slider to zero and t he three PWM to maximum. - Preset the end ILED current by using the ILED-UP slider - Adjust the GD START slider to start the Gradual Dimming UP sequence. - Repeat the same sequence with any ILED-UP and GD START position of the related sliders. Gradual Dimming Down - in order to visualize the effect, make sure the LED are activated to any value higher than zero, the PWM being set up as well. Preset the end ILED current by using the ILED-DOWN slider Adjust the GD START slider to start the Gradual Dimming DOWN sequence. Repeat the same sequence with any ILED-DOWN and GD START position of the related sliders.
