Texas Instruments TPS92518 | Demoboard TPS92518EVM Dual Buck Controller Evaluation Module

Description

The complete two-board TPS92518EVM solution provides a dual-channel, high-brightness LED currentregulator which is configurable via a graphical user interface (GUI). It is designed to operate with an inputvoltage in the range of 6.5 V to 65 V. The EVM is setup for default output currents of 538 mA per channel,easily adjustable to different currents up to 1.65 A, for an LED stack between approximately 3 V to nearly65 V. The TPS92518 provides high efficiency, high bandwidth, fast PWM dimming, SPI dimming, andadjustable off-time.
