A8519KLPTR-T is a PMIC - LED Drivers that belongs to the Texas Instruments’ control and switch family. It is suitable for many applications, primarily those involving LED lighting, industrial and automotive LED lighting, HVAC LED lighting, and LED switches.

The A8519KLPTR-T PMIC is a high-current, high-resolution, and high-efficiency monolithic integrated circuit (IC). It offers a wide range of adjustable brightness, input voltage, and output current options. It can also be easily programmed via its 6 adjacently spaced programming pins.

The A8519KLPTR-T PMIC can be used to drive standard 12V and 24V DC voltage lights from any AC or DC power supply. In addition, it can provide a variable voltage output for the driver for multiple applications. It also features a built-in reverse-output protection circuit that prevents damage to the circuit from reversed voltage.

The A8519KLPTR-T PMIC also features a load reduction circuit that allows the circuit to deliver maximum efficiency at up to 85% duty cycle. This reduces the overall power consumption by up to 50%. Additionally, the A8519KLPTR-T PMIC includes a graduated current limiting feature that provides an adjustable current limit and integrates pulse-width modulation (PWM) control.

The primary function of the A8519KLPTR-T PMIC is to provide a constant current, constant voltage power supply for LEDs. As current passes through the circuit, a resistance, or impedance, is activated in order to reduce the voltage and create stable output current. In this way, the voltage along the LED is kept at a constant level, providing stable and consistent illumination.

The A8519KLPTR-T PMIC is designed to support different application scenarios for LED lighting. This includes dimming and color changing, along with multiple dimming schemes, such as adjustable PWM, 1-bit logic dimming, and bimodal. All of these control types allow designers and technicians to customize the output of their lights for maximum efficiency, color consistency, and uniform lighting.

The A8519KLPTR-T PMIC is also designed to be highly reliable. It features built-in thermal protection and under-voltage lockout features for added protection. Additionally, the A8519KLPTR-T PMIC meets the requirements of the Underwriters Laboratory listing and comes with UL 94 V-0 certification.

In conclusion, the A8519KLPTR-T PMIC LED driver is an ideal choice for LED lighting applications. Its wide range of adjustable brightness, input voltage, and output current options, as well as its multiple dimming schemes, thermal protection, and UNDERWRITERS LABORATORY listing, make it an attractive option for many industries.
