New LED drivers from TI help designers reduce power consumption and improve total system efficiency in human-machine interface applications
Texas Instruments (TI) introduced a new family of LED drivers with integrated, independent color mixing, brightness control and a power-saving mode. The LP5018, LP5024, LP5030 and LP5036 enable smooth, vivid color and reduce system power consumption.
The devices are the industry's first to offer a 29-kHz dimming frequency, above human-audible range, to help designers of applications that use a human-machine interface, such as portable electronics, building automation and appliances, eliminate the noise typically heard when dimming lights. Additionally, designers can achieve smoother color and brightness-level adjustments compared to standard pulse-width modulation (PWM) solutions, by taking advantage of the devices' integrated 12-bit PWM generator.

Designers can download LP50xx graphical user interface software to easily configure the LP5018, LP5024, LP5030 and LP5036 LED drivers. Engineers can jump-start their designs with the LP5024EVM and LP5036EVM evaluation modules.
