LV5235VZ-MPB-H

PMIC - LED Drivers

LV5235VZ-MPB-H is a LED driver produced by Shindengen, a Japan-based supplier of automotive semiconductor systems and components. This LED driver is specifically designed to drive the LED lighting used in vehicles. It has a low power dissipation (<0.1W) and an wide input voltage range (9-45V).

Application Field

The LV5235VZ-MPB-H LED driver is designed for automotive applications where high efficiency, short circuit protection, tolerance to wide input voltage range, over temperature protection and inrush current protection are critical. It is suitable for LED lights used for tail lights, headlights, stop lights, position lamps, map lights, dashboard lights, fog lights and dome lights. The LV5235VZ-MPB-H LED driver is also suitable for other illumination tasks such as decorative lighting, signal light, etc.

Working Principle

The LV5235VZ-MPB-H LED driver employs a switching regulator to drive a LED or multiple LEDs. This regulator circuit works by rapidly switching the input voltage between 9V and 45v at a fixed frequency. In the ON state, the current flowing through the LEDs is controlled by a built-in constant current circuit. The regulator circuit is also thermally protected, providing a safe method to drive the LEDs. Additionally, the constant current circuit has a over current protection feature which will shut off the circuit and protect the LEDs if the current exceeds a defined limit.

The LV5235VZ-MPB-H LED driver features a low power dissipation, less than 0.1W, and a wide input voltage range of 9-45V, making it ideal for automotive applications where efficient operation, thermal protection, and inrush current protection are important. The LED driver is also equipped with a feedback circuit, allowing it to adjust its output current according to the LED\'s voltage, thus providing constant and stable current.

Summary

The LV5235VZ-MPB-H LED driver from Shindengen is designed for automotive applications where high efficiency and tolerance to wide input voltage ranges are important. This LED driver has a low power dissipation of less than 0.1W and an wide input voltage range of 9-45V, making it suitable for LED lighting applications. The LV5235VZ-MPB-H is equipped with a feedback circuit and a thermally protected, over current protection feature to ensure reliable and safe operation.
