MP4350DQ-LF-Z

PMIC - LED Drivers

LED drivers are a power management Integrated Circuit (PMIC) with the ability to control LED brightness in both DC and AC LED applications.

The MP4350DQ-LF-Z is a high efficiency LED driver capable of up to 100 LEDs in series. Its protection features include short circuit, low voltage, and over temperature, making it ideal for a variety of lighting applications.

Application Field

The MP4350DQ-LF-Z is designed for high efficiency LED lighting applications, such as automotive headlight, taillight and interior lighting, as well as signage, architecture and industrial lighting. It can be used in many types of single-channel (DC) and dual-channel (AC) configurations, including linear, constant current and dimming.

Working Principle

The MP4350DQ-LF-Z utilizes a unique voltage-mode, constant current mode control scheme to provide high efficiency and fast response time to dynamic changes in conditions. With its on-chip galvanic isolation of both channels, it allows the current to be independently adjusted to each LED string, while also providing total galvanic isolation between the system power supply and the LED array.

The MP4350DQ-LF-Z features a 0~400V operating range, between 25kHz and 200kHz PWM signal frequency. It can operate in both linear current mode and short circuit protection. Its robust low voltage input capability makes it an ideal choice for high efficiency and energy-saving applications.

Conclusion

The MP4350DQ-LF-Z is a high efficiency LED driver, suitable for a wide range of applications, from automotive headlight, taillight and interior lighting, to signage and industrial lighting. With its on-chip galvanic isolation and robust low voltage input capability, it is an ideal choice for high efficiency and energy-saving LED lighting applications.
