This document includes descriptions of the device, as well as the evaluation hardware and software. It also includes a schematic of the EVM. For related documents please check the LM3631 datasheet. If you need assistance regarding this device or the EVM, please contact your local TI sales representative. 1 Overview Texas Instruments' LM3631EVM helps designers evaluate the operation and performance of the LM3631 device. The LM3631EVM uses the LM3631 to create backlight power and LCD bias powers. Information about device characteristics and current ratings of LM3631 can be found in the datasheet. In order to facilitate ease of testing and evaluation of this circuit, the EVM contains a TI MSP430 microprocessor to provide easy communication via USB. The EVM also contains an external power supply connection for the VIN and VIO. Additionally, test points for signals can be found on the EVM. For evaluation purposes, the EVM has been tested over a 2.7V to 5.0V input range. This voltage range is within the absolute maximum input range of the LM3631. Users are cautioned to evaluate their specific operating conditions and choose components with the appropriate voltage ratings before designing this support circuitry into a final product. 2 LM3631 Device The LM3631 provides a high-efficiency backlight and positive/negative bias supplies for LCD drivers to address the power requirements of high-definition LCDs. Capable of driving up to 16 LEDs, the LM3631 is ideal for small format displays. A high level of integration and programmability allows the LM3631 to address a variety of applications without the need for hardware changes. 2.1 Features • • • • • • • • • 2.2 Drives up to 2 Strings of Maximum of 8 LEDs in Series with up to 25 mA per String Backlight Up to 90% Efficient LCD Bias Efficiency >85% 11-Bit Exponential or Linear Dimming External PWM Brightness Control for CABC Backlight Operation Positive Programmable LCD bias, 100 mA Negative Programmable LCD bias, up to 80 mA Two Positive Programmable LDO Reference Outputs, 50 mA and 80 mA 2.7-V to 5-V Input Voltage Range Applications Mobile Device LCD Backlighting and Bias 4 The LM3631EVM Evaluation Module SNVU370 – AUGUST 2014 Submit Documentation Feedback Copyright © 2014, Texas Instruments Incorporated LM3631 Device www.ti.com 2.3 2.3.1 Power Sequences Start-up After the nRST pin is set high and VBAT rises over the undervoltage lock-out (UVLO) limit, the LM3631 goes to Standby mode. Before entering Standby mode, references and bias currents are enabled (bias delay typically 200 μs), and registers are read from OTP (EPROM read delay typically 700 μs). In Standby mode references and bias currents are enabled, and I2C writes are allowed. Oscillator, LCD powers, and backlight are disabled. During an I2C write, the oscillator is enabled. When LCD_EN is set to high (pin or bit), the start-up sequence is started. During the start-up sequence LDO_CONT, LCD Boost, and LCD bias powers are started. If the LDO_CONT is disabled, the start-up sequence goes directly to LCD Boost start-up. LDO_CONT start-up: LDO_CONT is enabled. Programmable delay of 0 - 200 ms. LCD Boost start-up: LCD Boost is enabled. Waits until Boost output voltage is reached 90% of target value. LCD bias start-up: Enables sequentially LDO_VPOS, CP_VNEG, and LDO_OREF according to start-up delay settings. After the LCD bias start-up, the LM3631 enters backlight start-up mode if the BL_EN bit is set to ‘1’ and the PWM brightness value is different than 0. Even though backlight is not enabled, LCD remains active. If backlight is enabled and the BL_EN bit or PWM brightness value is set to '0', backlight is disabled; LCD remains active. 2.3.2 Shutdown If LCD_EN is set to ‘0’, the device enters shutdown. In shutdown the backlight is shut down first (if it is enabled) . After backlight shutdown is completed, the device enters LCD Bias shutdown. In LCD bias shutdown LDO_VPOS, CP_VNEG, and LDO_OREF are shut down sequentially according to shutdown delay settings. After the LDO_VPOS, CP_VNEG, and LDO_OREF shutdown sequence is complete, the LCD Boost and LDO_CONT (if they are enabled) are shut down. LDO_CONT is shut down after adjustable delay (0 – 200 ms). Then the device enters Standby mode. If there is a fault situation (UVLO, Thermal, backlight boost short circuit, backlight overcurrent, LDO_OREF overcurrent, VPOS overcurrent, and CP short circuit), the device starts the shutdown sequence. 3 Evaluation Module The LM3631 evaluation module consists of an evaluation board (hardware) and evaluation software. 3.1 Quick Setup This section shortly describes how to connect and setup LM3631 EVM. (A) Connect external power supply to VIN and GND of EVM. Set the voltage to, for example, 3.6 V. (B) Connect USB cable to EVM. (C) Start the Evaluation program from white arrow on left hand top corner. (D) Check the nRST and LCD_EN boxes in General tab. Program reads the registers automatically. (E) By now the LM3631 should be giving out VPOS and CP_VNEG voltages. Also LCD boost is on. Backlight is off. (F) Setting backlight on: • Switch to Backlight tab. • Select "I2C Register" -control from Brightness Mode -pulldown menu. • Set the brightness value from Brightness-slider. • Push the Update Brightness -button SNVU370 – AUGUST 2014 Submit Documentation Feedback The LM3631EVM Evaluation Module Copyright © 2014, Texas Instruments Incorporated 5 Evaluation Module 3.2 www.ti.com Setting Up The LM3631EVM is connected via USB to the computer. The EVM is controlled with special evaluation software. An MSP430 microcontroller is used in the EVM to provide easy I2C communication, nRST-pin, LCD_EN-pin, OTP_SEL-pin, and PWM control with the LM3631 via USB. The EVM is powered by default via USB. LM3631 device is powered from external power supply. The external power supply need to be connected to the green connector near USB connector. LM3631 evaluation software (available at www.ti.com) uses the LabVIEW runtime engine which needs to be installed (if not installed previously). The LM3631 Evaluation Software Installer includes the setup.exe which installs the LM3631 evaluation software and LabVIEW runtime engine to Windows computer. Figure 1. Evaluation Software Setup File Running the setup opens up the installer, which prompts the Destination Directory where the program is to be installed. Note that user needs to have administrator rights to be able to install this program. 6 The LM3631EVM Evaluation Module SNVU370 – AUGUST 2014 Submit Documentation Feedback Copyright © 2014, Texas Instruments Incorporated Evaluation Module www.ti.com Figure 2. Software Installation When the board is connected to a computer, Windows should recognize it automatically and start to install the driver. A “Found New Hardware” dialog box will prompt user to locate the missing driver. Select “No, not this time” and continue with “Next”. Select “Install from a list or specific location (Advanced)” to install the driver. Select the directory where the TI_CDC_Virtual_Port driver is. Windows should now install the driver, and the PC can communicate with the EVM using a virtual COM port. If Windows cannot find the driver, user needs to manually install the TI_CDC_Virtual_Port driver from the Device Manager. Once the board is connected and the driver is installed, the red LED should blink on the evaluation board, indicating the board is recognized. The evaluation software scans the USB ports automatically. If the board is not found, the software should prompt regarding this issue. The USB address can be changed manually from the evaluation software; switching to another USB port also might solve the issue.

By default the LM3631 is controlled by the MSP430 microcontroller via USB. VDD voltage come from USB, and the I2C traffic is controlled with the microcontroller. The evaluation hardware also allows external control: the VDD can be fed externally via connector and with jumper selection. The I2C traffic, nRST-pin, LCD_EN-pin, OTP_SEL-pin, PWM and FLAG-pin control can be changed from MSP430 control to external control using a pin header. The LED driver control can be changed from 4 to 8 WLEDs and from 1 to 2 strings. The pin header enables current measurement to the LED drivers. A test point (header) exists for some of the device pins. Figure 3.
