The new offering consists of the Atmel MSL2021, MSL2023 and MSL2024 devices that drive one dominant LED string with a linear controller and one colour LED string with a low-side buck controller to achieve the target correlated colour temperature (CCT) coordinate, and replicate the colour spectrum to attain a high CRI value. They also feature a look-up table in the EEPROM for the programming of accurate profiles to follow the desired CCT compensation curve, and to lower BOM cost.
The linear controller for white LEDs in the device family adaptively controls the headroom of any AC/DC or DC/DC, isolated or non-isolated topology, while external MOSFETs give designers the flexibility of choosing LED currents and LED string lengths. Several dimming options and I2C interface provide flexibility and control.
The device are available for 1,000-piece quantities are priced as follows: MSL2021 starts at USD $3.10, MSL2023 starts at USD $2.74 and MSL2024 starts at USD $2.52. Evaluation kits are also available.
