6-CHANNEL LIGHT EFFECT LED DRIVER

Transcription

1 -CHANNEL LIGHT EFFECT LED DRIVER DESCRIPTION ISFL/ISFLA is a -channel light effect LED driver which features two-dimensional auto breathing mode and an audio modulated display mode. It has One Shot Programming Mode and PWM Control Mode for RGB lighting effects. The maximum output current can be adjusted in levels (ma~ma). FEATURES Supply voltage range from.v to.v Two groups RGB, single color LED breathing system-free pre-established pattern independently controlled automatic and semiautomatic breathing system-free pre-established pattern independently controlled outputs of PWM steps levels programmable output current Audio mode with AGC function Cascade for the synchronization of chips QFN- (mm mm) package QUICK START PROCEDURE The ISFL/ISFLA evaluation board is fully assembled and tested. Follow the steps listed below to verify board operation. Caution: Do not turn on the power supply until all connections are completed. ) Short JP to connect by board MCU. ) Connect the VDC power to the connector (TP&TP). ) Turn on the power supply/plug in the Micro USB Pay attention to the supply current. If the current exceeds A, please check for circuit fault. EVALUATION BOARD OPERATION The ISFL/ISFLA evaluation board has five display modes. Press K to switch configurations. ) lamps breathe at the same time ) The RGB monochromatic breathes ) RGB audio mode ) lamps breathe one by one ) lamps audio mode Note: ISFL/ISFLA solely controls the FxLED function on the evaluation board. Figure : Photo of ISFL/ISFLA Evaluation Board RECOMMENDED EQUIPMENT.V, A power supply ABSOLUTE MAXIMUM RATINGS.V power supply Caution: Do not exceed the conditions listed above, otherwise the board will be damaged. SOFTWARE CONTROL J default setting is closed (short). If it is set to open, the MCU's,, and CLK pin will be high impedance (open-drain) and external control is allowed. Follow the steps listed below for external control. ) Open J to enable external control ) Pull-up the to. ) Connect the VDC power to the connector (TP&TP). ) Turn on the power supply/plug in the Micro USB Pay attention to the supply current. If the current exceeds A, please check for circuit fault. ) Start external IIC control. Caution: If J is closed (shorted), user can t connect the user s MCU, otherwise the user s MCU (maybe.v) will connect to evaluation bard s MCU (.V) and maybe damaged.
