1 Description

The complete two-board TPS92518EVM solution provides a dual-channel, high-brightness LED current regulator which is configurable via a graphical user interface (GUI). It is designed to operate with an input voltage 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 nearly 65 V. The TPS92518 provides high efficiency, high bandwidth, fast PWM dimming, SPI dimming, and adjustable off-time.
