The DS3992Z-18N+ is a mature PMIC (Power Management IC) optimized for lighting, ballast controllers and others. This dedicated IC is suitable for outdoor installations such as street lights, parking lots and building entrances. Thanks to its robust design, it can even handle power instabilities often caused by high-voltage fluctuations.

The DS3992Z-18N+ proves to be versatile, joining several different Inputs types, including both AC and DC sources, and other power management components, making the design of lighting solutions fast and easy. Also, innovations like Self-Start, brownout protection and Auto configuration, along various protection features, provide a high level of system integrity.

In terms of output current and voltage, the DS3992Z-18N+ features a high peak current capability of 20A and can regulate voltage from 5V to 7V. It also provides an output signal to the PFCB (Power FACTOR (Corrector Board) and a signal present at the output to indicate the remaining output voltage.

The DS3992Z-18N+ allows the design of a low-noise LED dimmable solution. It is capable of driving high power buck LED drivers and off-line LED drivers efficiently and it supports multiple dimming type solutions, like 0-10V, PWM and external programming. Additionally, various diagnosis functions such as over-temperature, under-voltage and overload protection ensure the reliability and safety of lighting applications.

In order to provide the needed flexibility and adaptability, the IC allows the programming of the dimming enable pin and its hysteresis. The design of two independent enable pins allows the different outputs of the DS3992Z-18N+ to be on at the same time, even when the enable input is the same.

To summarize, the DS3992Z-18N+ presents a reliable and versatile solution for any power management design in lighting, ballast controllers and other related applications. With its flexible inputs and its high-voltage capability, it can be used for different types of outdoor solutions, such as street lights, parking lots and building entrances.
