LT8355-1: 60VIN/120VOUT Dual LED Controller with Exponential PWM and Scalable Dimming

Introducing the LT8355-1: The Ultimate Dual-Channel DC/DC Controller for High Current LED Applications

Looking for a reliable and efficient way to drive two strings of high current LEDs? The LT8355-1 dual-channel DC/DC controller is a solution. With its fixed frequency, current mode architecture, this controller ensures stable operation over a wide range of supply and output voltages, making it the perfect choice for a wide range of applications.

One of the key features of the LT8355-1 is its voltage feedback pins, which serve as the inputs for several LED protection features. This allows the controller to operate as a constant-voltage source, ensuring that your LEDs are always running at the right voltage.

The LT8355-1 also features a unique sensing system that allows it to detect output current at the high or low side of the load. This makes it easy to program the output current for each channel, with CTRL1 and CTRL2 inputs for each channel, respectively.

The LT8355-1 also comes equipped with a PWM input and PWMTG high side PMOS driver, providing you with precision time-based LED dimming capability. Whether you’re looking to dim your LEDs with an external digital signal or choose from one of 128 internally generated, precision, exponentially spaced dimming ratios, the LT8355-1 has got you covered.

Whether you’re working on high voltage LED applications, automotive head lamps/running lamps, or an accurate current limited voltage regulator, the LT8355-1 is the ultimate choice for your high current LED needs. Order yours today and experience the difference.
