Texas Instruments (TI) introduced a new family of LED drivers with integrated, independent colour mixing, brightness control and a powersaving mode. The LP5018, LP5024, LP5030 and LP5036 enable smooth, vivid colour and reduce system power consumption.
According to TI, 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 colour and brightness-level adjustments compared to standard pulse-width modulation (PWM) solutions, by taking advantage of the devices’ integrated 12-bit PWM generator.
Key features and benefits of the LP5018, LP5024, LP5030 and LP5036 LED drivers include high-resolution PWM dimming and ultra-low quiescent current. Also, 18-, 24-, 30- and 36-channel options provide independent colour mixing and brightness control, while three integrated, programmable banks enable simplified software coding and ease of design.
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.
