LT3599EUH#PBF

LT3599EUH#PBF is a PWM-controlled peripheral power management integrated circuit (PMIC), belonging to the LED Driver family. Specifically designed and manufactured to control the power supply delivered to an LED, this device provides an adjustable output power solution for an LED and conserves power by switching off unused circuitry not directly related to illuminance.

This power management integrated circuit is capable of high power up to 2.5A, providing a wide range of output voltage (3V to 24V), featuring one independent high-current (2.5A) output stage and two low-current (50mA and 300mA) output stages, as well as several high- and low-side enable pins. The low-side enable pins enable the low- and high-current output stages separately, which allows for effortless control of those output stages. The DRV and CT pins allow for adjusting of the amplitude and frequency of the PWM output, respectively.

The LT3599EUH#PBF is suitable for applications where a low cost, low-power, PWM enabled LED Driver is needed, such as LED lighting, industrial, and medical controls. The device provides a wide input voltage range from 4V to 24V and is able to operate under -40°C to 125°C junction temperatures. Overall, the LT3599EUH#PBF is an excellent choice for simple, low sidelights and LED lighting applications.

The working principle of the LT3599EUH#PBF is based on a Pulse Width Modulation (PWM) technique. This technique, due to its high efficiency, is used to control the power of an LED with a higher precision than other control methodologies (i.e. analog circuits). The device works by first processing the AC voltage input into a rectified DC voltage. This DC voltage is then used to control the width of pulses applied to the LED, which in turn controls the current that is supplied to the LED. The frequency at which the pulses are applied can be adjusted by changing the value of the CT pin.

The LT3599EUH#PBF has some unique features that set it apart from similar varieties in the LED Driver family. Most notably, it is capable of very smooth dimming, making it an excellent choice for applications where a smooth, consistent light intensity is desired. Additionally, the device includes a built-in thermal shutdown logic and an overvoltage protection function, which helps ensure safe operation of the power circuit. These additional features make the LT3599EUH#PBF an excellent choice for powering various types of conductive lighting devices.

In conclusion, the LT3599EUH#PBF is an ideal choice for applications that require versatile, low-cost and low-power PWM-controlled LED Drivers. It is capable of high power up to 2.5A, providing a wide range of output voltage (3V to 24V), featuring one independent high-current output stage, two low-current output stages, and several high- and low-side enable pins. The device is well-suited for LED lighting, industrial, and medical applications, and its features make it an excellent choice for powering various types of conductive lighting devices.
