The LT3755HMSE-2#PBF is a 4-channel LED driver utilizing a buck-boost topology. It has mixed current control, along with programmable spread spectrum, and can support up to 4 LED strings. Different LED strings can be connected to the same VIN, allowing higher overall current than with a single LED string. This makes the LT3755HMSE-2#PBF an excellent choice for applications that require high current and where space is an issue. The device can also be used in automotive applications, as it is AEC-Q100 qualified.

The LT3755HMSE-2#PBF is designed for applications that require high efficiency and peak current, such as LED backlighting, LED displays and LED lighting fixtures. Its wide input voltage range, adjustable output current and efficient step up/down conversion make it ideal for use in a variety of LED applications. The device also offers an adjustable spread spectrum mode, which helps reduce EMI and noise.

The LT3755HMSE-2#PBF has built-in protection features including over-voltage protection and thermal shutdown. The device is equipped with mixed current control, which allows the user to select the desired output current. The device also supports adjustable output current spread spectrum mode, which can reduce EMI and noise. In addition, the device supports external clock synchronization and enables fast wake-up time.

The LT3755HMSE-2#PBF is available in a compact HTSSOP-16 package and operates over a wide input voltage range (4.5V to 60V). The device is easy to configure and supports up to 4 LED strings with a programmable output current from 0.5A to 10A (typ). The built-in PFM control allows for higher efficiency and lower over current and EMI levels.

In summary, the LT3755HMSE-2#PBF is a high performance, highly integrated and cost effective driver that is suitable for a wide range of LED applications. It offers a high efficiency, wide input voltage range, adjustable current, spread spectrum, and built-in protection features, making it an excellent choice for LED backlighting, display, and lighting fixtures.
