Tel:886-3-5645656 Fax:886-3-5645626 DM413 DM413 3-CHANNEL CONSTANT CURRENT LED DRIVERS WITH PROGRAMMABLE PWM OUTPUTS General Description DM413 is a PWM enabled LED driver specifically designed for LED lighting or display applications. It incorporates shift registers, data latches, 3-channel constant current circuitry with current value set by 3 external resistors, and built-in oscillator for PWM functioning. Data and clock buffer outputs are designed for cascading another chip. Additionally the Output Polarity Reverse function is designed for more high power LED applications. Features z z z z z z Maximum constant current outputs: 100mA determined by three external resistors Maximum sinking output voltage: 17V Maximum serial-in clock frequency: 20 MHz Built-in buffers for cascading clock and data to next driver PWM free-running capability (refresh rate (~ 400 Hz) with internal oscillator (~ 6.5 MHz)) Selectable modes for PWM control: ‹ 8-bits luminance data with PWM current outputs (8 bits mode) ‹ 8-bits luminance data and 6-bits global brightness data (14 bits mode) ‹ 8-bits luminance data and 5-bits individual color correction data (13 bits mode) Output polarity reverse function TTL/CMOS compatible input Power supply voltage: 3.3V ~ 5.5V z z z Applications z z z LED Decorative Lighting Indoor/Outdoor LED Video or Message Display PWM Signal Generator Package Types z SSOP16, SOP16 Version:PRE.006 Page 1 3-CHANNEL CONSTANT CURRENT LED DRIVERS 、、, Unauthorized reproduction, duplication, use or disclosure of this document will be deemed as infringement.
