ATMEL Launches Unique Dual Channel LED Driver

ATMEL Corporation, a leading manufacturer of microcontroller and touch technology solutions, announced the launch of three new dual channel solid state lighting (SSL) LED drivers to provide accurate color control for dual color LED light engines. In addition, the LED driver provides the most efficient power management for high CRI LED lamps with the least number of components.These LED drivers, including ATMEL msl2021, msl2023 and msl2024, are ideal for applications such as general lighting, residential and commercial lighting, architectural lighting and situational lighting. All devices can form a complete system solution with ATMEL AVR MCU or arm processor based MCU for various light source and lamp configurations.Compared with the existing LED driver, the new msl2021 / 23 / 24 LED device has several unique advantages:

ATMEL Launches Unique Dual Channel LED Driver 1

The new device uses a linear controller to drive a main LED lamp string, and a low side step-down controller to drive a color LED lamp string to achieve the coordination of target related color temperature (CCT), and copy the chromatography to achieve high CRI value.The new device has EEPROM look-up table, so designers can prepare accurate configuration files, follow the required CCT compensation curve, and reduce the overall bill of materials (BOM) cost.In the device family, the linear controller for white LEDs adaptively controls the dynamic margin of any AC / DC or DC / DC, isolated or non isolated topology. At the same time, the external MOSFET provides designers with the flexibility to select LED current and LED string length.

For additional flexibility and control, several dimming options and I2C interfaces are provided.Tushar dhayagude, product director of ATMEL led, said: "White spot control of LED lamps is a key challenge for designing high-performance general, architectural or situational lighting. By controlling two lamp strings that usually contain white, red or amber LEDs, msl2021 / 23 / 24 LED devices solve this key problem, provide accurate white control, and provide lamps with excellent power efficiency, flexibility and wide power level The main features of the three new devices include:

Msl2021 first LED Driver with integrated temperature compensation for color LED stringsMsl2023 provides I2C serial port and built-in pulse width modulation (PWM) generatorMsl2024 with separate PWM input pins

Price and supplyATMEL can now provide new devices and order 1000 pieces at the following prices:Msl2021 starts at $3.10

ATMEL Launches Unique Dual Channel LED Driver 2

Msl2023 starts at $2.74Msl2024 starts at $2.52To speed up the design, you can obtain the evaluation tool kit through your local sales representative. The new kit includes an isolated AC / DC power supply, an integrated LED load circuit board with a white and red LED string, and an on-board AVR MCU connected to I2C interface and USB / parallel bridge for LED driver programming.
