The LT3519EMS-2#TRPBF LED Driver is a LED-specific power management integrated circuit (PMIC) designed to provide the current and voltage necessary to control the brightness of LEDs. It is an ideal choice for applications requiring the accurate delivery of power to LEDs over a wide range of low battery voltages. In addition, it features an integrated current source to accurately control LED current and ensure compliance with regulatory requirements.

The LT3519EMS-2#TRPBF features a high accuracy integrated comparator, precision voltage and current references, a high/low side gate driver, and a voltage extinction pin. The comparator monitors the IMON/LEDVIN pin to set the LED current on the IMON/LEDVOUT pin: matching or up to 600% higher. The extinguished voltage pin (EXV) can be used to reduce current consumption by up to 80%.

Furthermore, the LT3519EMS-2#TRPBF supports a wide input voltage range from 2.25V to 24V. It also features an extended LED current range from 2.5mA to 600mA. Additionally, the device generates up to 3.3V or 7V output on the LED output pin. All these capabilities make the LT3519EMS-2#TRPBF suitable for driving various LED applications, such as automotive interior and exterior lighting, LED billboards, and signage applications.

The LT3519EMS-2#TRPBF works in buck or boost configurations, with a maximum switching frequency of 1MHz. It comes with an integrated low-side totem-pole controller, resulting in an efficient solution with no additional protection components. The device also features excellent thermal performance with a thermal pad in both thermally enhanced 8-pin TDFN and 6-pin MSOP packages.

The LT3519EMS-2#TRPBF also features an advanced current control architecture with a wide range of output currents. A patented constantly regulated output circuit limits in-rush current during start-up and shutdown events, resulting in excellent instantaneous output current rise time and fall time. Moreover, the device requires minimal external components for operation, thereby enabling a small and cost-effective design. It also comes with an integrated on/off control pin for PWM dimming, enabling it to be controlled by microcontrollers or other digital devices.

In conclusion, the LT3519EMS-2#TRPBF is an ideal LED driver for applications requiring extended range output current control, minimal external components, and advanced current control architecture. It provides the accuracy and features necessary to efficiently control the brightness of LEDs over a wide range of low battery voltages. Plus, it offers an excellent performance across different environmental conditions, making it suitable for a wide range of applications.
