PMIC (Power Management Integrated Circuit) - LED Drivers generally refers to integrated circuits that manage the power on an electronic device. The LT3795HFE#PBF is a high efficiency, synchronous flyback switching regulator with an integrated High-current/+Vboost LED driver, designed to drive up to 60 LEDs in series. It is an ideal driver for LED backlights used in displays, LCD TVs, and LCD monitors.

The LT3795HFE#PBF supports up to 25V LED open circuit voltage and allows LED series voltage compensation up to 10V. This feature is unique in its class and provides flexibility when powering side-by-side LEDs with varying VF (volt forward).

The LT3795HFE#PBF has several features that make it an ideal choice for LED driver applications. It features a high switching frequency up to 1.2MHz and a wide input voltage range of 4V to 28V, allowing it to be operated directly from Li-ion batteries. Additionally, the device is capable of simultaneously driving up to 60 LEDs in series with up to 25V open circuit voltage. It also features frequency jittering to reduce EMI.

The LT3795HFE#PBF is a high efficiency, synchronous buck-boost switching regulator with an integrated High-current/+Vboost LED driver. The buck-boost architecture allows for easy control of the output voltage for various LED configurations. The device also features a low quiescent current of less than 5mA, which further increases system efficiency. In addition, the LT3795HFE#PBF offers both high-side and low-side current sensing for LED current control.

As with many LED drivers, the LT3795HFE#PBF offers an adjustable switching frequency, allowing designers to choose the best frequency for the application. The adjustable frequency helps to eliminate the need for external components, resulting in a reduced BOM (bill of materials) cost. The device also offers internal soft start, over-temperature protection, under-voltage lockout, and thermal shutdown. Finally, the device is offered in both through-hole and surface-mount packages, allowing it to be used in a variety of applications.

The LT3795HFE#PBF is a versatile LED driver with a variety of features and options. The wide input voltage range allows it to be used with multiple sources, including Li-ion batteries, and the adjustable switching frequency lowers the BOM cost. The device also features low quiescent current, making it an ideal choice for mobile applications. In addition, the adjustable frequency jittering helps to reduce EMI. The LT3795HFE#PBF is an ideal driver for LED backlights used in displays, LCD TVs, and LCD monitors.
