The ZXLD1374EST-20TC LED Driver is a surge protection LED driver with wide input voltage range and high LED driving current, which is suitable for many applications, such as indoor and outdoor LED lighting. It is a PMIC - LED driver that utilizes adjustable current control, providing high reliability, efficiency and system performance.

The ZXLD1374EST-20TC LED Driver is capable of driving up to 600mA of constant current per channel with a single channel of output. The driver also has protection features built-in for reverse, over-voltage and surge protection, and can be used in a wide range of conditions. The external components required for the driver are few and simple, allowing for a small and compact design with simple implementation.

The ZXLD1374EST-20TC LED Driver operates on a simple push-or-pull operation. When an appropriate voltage is applied, the driver is pushed into the "ON" state with a constant current output. Conversely, when the voltage is removed, the driver is pulled into the "OFF" state with no current output. The current value is adjustable via an external resistor, allowing the output current to be set as required by the specific application.

The working principle of the ZXLD1374EST-20TC LED Driver relies upon an internal N-channel MOSFET, used in a linear configuration. When the voltage is applied, a weak pull-up current is used to slowly increase the voltage between the Gate and Source pins of the internal MOSFET. This increasing voltage causes the source current to increase, and since the load current is determined by the external resistor connected to the output, the total LED load current will be adjusted accordingly.

The ZXLD1374EST-20TC LED Driver is suitable for numerous applications, including LED lighting for both indoor and outdoor applications, LED backlighting for LCD displays, LED signage and indicator lighting, automotive LED lighting, and many more. The wide input voltage range, combined with its high LED driving current, offer excellent flexibility and reliability.

The ZXLD1374EST-20TC LED Driver is a highly reliable, efficient, and versatile LED driver, capable of providing robust surge protection to LED lighting application while maintaining low power consumption. Its adjustable current control feature gives users the flexibility to adjust the LED current according to their application’s needs, while its N-channel MOSFET technology ensures reliability and constant current output.
