In this article we will look at the applications of SP7121EK-L/TR, as well as its working principle.

SP7121EK-L/TR Applications

The SP7121EK-L/TR is an LED driver that is extremely versatile, with applications spanning solid state lighting, automotive applications and consumer electrical appliances. In solid state lighting, the LED driver can be used to control LED lighting strings, replacing traditional incandescent, fluorescent and halogen bulbs. The LED driver is also compatible with automotive LED lighting applications and has a wide range of outputs, from 12V to 78V. Finally, the LED driver can be used in consumer electrical appliances, such as home appliances, TV and audio/video.

SP7121EK-L/TR Working Principle

The SP7121EK-L/TR is a full-bridge LED driver based on the power MOSFET. The power MOSFETs used in this driver are designed with low on-resistance, allowing for high currents to be switched. The driver also features an on-chip, spread spectrum PWM so that the peak current is accurately distributed across the LEDs, minimizing EMI (Electro-Magnetic Interference), an important factor in many applications. The driver also includes current-sense circuitry, allowing it to detect short-circuits or open-circuits within the LED string. This in turn allows the driver to be monitored and controlled, providing a more reliable, safe and energy-efficient solution.

Conclusion

The SP7121EK-L/TR is a full-bridge LED driver that can be used in a wide variety of applications. Its low on-resistance power MOSFETs, as well as its integrated current-sense circuitry, provide a highly reliable, safe and energy-efficient solution. The driver is versatile enough to be used in solid state lighting, automotive applications and consumer electrical appliances such as home appliances, TV and audio/video.
