LT3755EUD#PBF

The LT3755EUD#PBF is a high voltage integrated switch mode power supply (SMPS) and LED driver. It contains a buck topology PWM step-down regulator, a current-mode buck controller, and a linear regulator. It is designed specifically to drive LED lighting applications, with applications including general LED lighting, commercial LED displays and outdoor LED lighting. With its high efficiency and small size, the LT3755EUD#PBF is ideal for LED lighting control.

The LT3755EUD#PBF contains an integrated PWM step-down regulator, a current-mode controller, and a linear regulator. The step-down regulator provides over-current protection and automatic frequency scaling at light and heavy load conditions. The current-mode controller features a constant on-time mode that provides the user with the lowest possible switching losses and improved efficiency. The linear regulator provides the required minimum load current for proper operation of other components in the system. The LT3755EUD#PBF is programmed through a simple two-wire interface using a Slave Address and Data Line. The user can select the digital output control, adjust the current limit, or select the frequency of operation.

The LT3755EUD#PBF is ideal for LED lighting applications as it offers a solution that is simple to use, efficient, and extremely low noise. It provides a combination of protection features that include thermal protection, over-voltage protection, over-current protection, and programmable frequency scaling. This helps prevent any problems that could occur from over-driving the LEDs. Additionally, the device includes a wide input voltage ranging from 5V to 60V and is rated for LED current ratings up to 8A. This allows for more efficient design and higher brightness effects.

The LT3755EUD#PBF also includes a wide range of features for user control. It provides PWM dimming, low-side current regulation, over-voltage protection, over-current protection, and selectable Low EMI or power saving modes. Additionally, the LT3755EUD#PBF features On-chip Diagnostics, which provide an easy way to debug the solutions. In summary, the LT3755EUD#PBF is the ideal choice for LED lighting applications as it provides attractive features, better robustness, and assures low cost solutions.
