LED drivers containing Linear Technology Corporation’s ZXLD1362ET5TA chips are designed to control the luminous intensity of LEDs in a variety of applications. The chip combines a low side linear current regulator circuit, voltage regulator circuits and a high-side dimming control circuit to allow for smooth and reliable operation. By combining both analog and digital circuitry, the device can be used to adjust the brightness of any type of LED without the need for manual tweaking or adjustments.

The ZXLD1362ET5TA is a highly integrated dual-channel, high efficiency boost converter with two channels independently adjustable. It is designed to be used in power-limited applications such as strobe cameras, stop/start cars, uninterruptible power supplies, and automotive headlights. The chip’s built-in dimming control circuit can be used to adjust the luminance of LEDs with a minimum commissioning time. Additionally, the device features safety elements such as over-current and short circuit protection.

The device operates in a boost mode, boosting the voltage from a lower level to the desired level for the LED. It uses a current regulated topology to control the LED current, leading to improved LED uniformity and a better LED life time. The chip also features an adjustable PWM dimming control circuit, which enables the LED to be dimmed from 0.01V up to the maximum LED output voltage. This makes the device suitable for applications where the LED needs to be dimmed without changing the LED’s maximum voltage.

In terms of application, the ZXLD1362ET5TA is primarily used to control the current and brightness of LEDs in automotive illumination applications. It can be used to drive a large number of high brightness LEDs with a single device, making it ideal for applications such as stop/start braking systems and headlights which require multiple high-brightness LEDs to be illuminated.

The ZXLD1362ET5TA is also suitable for other general lighting applications, particularly those where dimming is required such as retail and commercial displays. The chip can also be used in industrial control and telecommunications applications where uniform lighting control and dimming are necessary. Furthermore, due to its high efficiency and high accuracy, the chip can be used in energy-saving applications.

Overall, the ZXLD1362ET5TA is a highly integrated LED driver device that can efficiently and accurately drive a variety of LED lighting applications. The device is well suited to automotive applications such as headlights and brakes, as well as general lighting applications such as retail and commercial displays. Thanks to its built-in dimming control circuit, the chip allows for easy adjustment of the LED luminous intensity without manual tweaking or adjustments, making it a simple and effective way to control LEDs.
