Four Channel Led Driver


Applications Colored, large-character LED signs Scrolling, colored marquees Architectural lighting High intensity monochrome displays Large video and graphic displays DATASHEETS A6280 Datasheet SAMPLE & BUY Digi-Key Corporation (Distributor, Allegro & Sanken Each of these inputs has buffered outputs to drive the next chip in the chain. The A6280 is a 3-channel constant current LED driver that has a wide range of output currents. The LED brightness is controlled by performing PWM control on the outputs. check over here

The maximum current is set by an external resistor. All the internal latched registers are loaded by a 31-bit shift register. Sign Up 3 × 10-bit PWM brightness settings 3 × 7-bit dot correction current settings 5 to 17 V operation Wide output current range, 10 to 150 mA per channel Serial Contact Sales English 中文 日本語 Current Sensor ICs Magnetic Digital Position Sensor ICs Magnetic Linear and Angular Position Sensor ICs Magnetic Speed Sensor ICs Motor Driver and Interface ICs Regulators http://www.ti.com/lit/gpn/tlc5973

Four Channel Led Driver

The brightness data of the PWM signal for each LED is stored in three 10-bit registers. A large number of A6280s can be daisy chained together and controlled by just four control signals (clock, serial data, latch, and output enable). RECEIVE PRODUCT ALERTS We'll notify you when there are updates to this product.

Date of status change: December 2, 2013. The packages are lead (Pb) free with 100% matte-tin leadframe plating. The A6280 controls LED brightness with a Pulse Width Modulation (PWM) scheme that gives the application the capability of displaying a billion colors in an RGB cluster. Adp8140 This helps reduce the pin count of the A6280.

The peak value for each LED can be adjusted (dot-corrected) to compensate for mismatch, aging, and temperature effects. The A6280 is designed to minimize the number of components needed to drive LEDs with large pixel spacing.

The A6280 is supplied in a 16-pin dual in-line (DIP) package (suffix ‘A’) and in a 16-lead QFN (suffix ‘ES’) package. Max16814 The remaining bits are used for the data. Also, VIN can be tied to the LED voltage supply bus, thus eliminating the need for a separate chip supply bus or an external regulator. There are no news items available for this product.

To further lower the A6280 pin count, the PWM clock and the serial bus clock share the same pin and work concurrently to control LED brightness and to load data.
