LEDs, or light-emitting diodes, are becoming increasingly popular in a variety of applications due to their low cost, low power consumption, and long life. However, these devices require compatible and efficient drivers for best results. ESPT060E-1400-42 is a LED drivers designed for applications such as LED display, lighting, automotive and others. In this article, we will discuss the application field and working principle of this LED driver.

ESPT060E-1400-42 is a three channel DC/DC constant current LED driver. This LED driver is able to drive three different LED strings in parallel, while maintaining constant current in each string and providing smooth transitions of light level. It has a range of input voltage from 7V to 24V and output current from 30mA to 700mA. This driver also contains protective features such as Over voltage protection, Over current protection, Over temperature protection, Short circuit/open circuit protection, and Under voltage lockout.

ESPT060E-1400-42 has a wide range of applications due to its many features. Its efficient and reliable functionality makes it suitable for indoor lighting applications such as backlighting, hallway, office, and home lighting. Its wide input and output range makes it ideal for automotive headlights and dashboards. It can also be used to drive LED display systems and other industrial application.

This LED driver’s working principle can be understood from its block diagram. It is composed of full bridge rectifier, DC/DC converter, current sense amplifier, loop compensation, and Thermal shutdown/open circuit detection. The rectifier circuit takes in AC voltage and converts it to DC voltage. The DC/DC converter then takes the DC voltage and converts it to the desired output voltage. The current sense amplifier measures the output current and adjusts it to the desired value. The loop compensation ensures that the output current is well regulated as the input voltage changes. The thermal shutdown/open circuit detection prevents any damage from excessive temperature or open circuits.

In conclusion, ESPT060E-1400-42 is an efficient and reliable LED driver suitable for a wide range of applications. Its wide input and output ranges make it suitable for lighting, automotive, and display applications. Its working principle is based on full bridge rectifier, DC/DC converter, current sense amplifier, loop compensation, and Thermal shutdown/open circuit detection, which ensures efficient functioning and safety of the driver.
