PMIC (Power Management Integrated Circuit) refers to an integrated circuit, usually a silicon chip, that integrates numerous power supply functions to reduce the number of components and reduce the overall cost of the power technology. A wide range of PMIC products are available in the market, and one of them is the DC DC Switching Regulator, represented by the MP1494SGJ-Z. This article will discuss the application field and working principle of the MP1494SGJ-Z and explain how this device is used in a variety of industries.

Application Field of MP1494SGJ-Z

The MP1494SGJ-Z is a high voltage, highly integrated DC DC switching regulator, specifically designed for light emitting diode (LED) applications. It is ideal for driving high-voltage LEDs in series or arrays. The device features a wide adjustable output voltage range of 2.4 V to 350 V, adjustable switching frequency of 9 kHz to 1.2 MHz and high efficiency of up to 96%. It also has a wide dimming range of 1% to 100% and a high-power factor of up to 1.0.

The MP1494SGJ-Z is highly suitable for high-powered LED lighting applications. It is also suitable for LED TV backlight, architectural lighting, LED signs and individual LED light source applications. In addition, the device’s adjustable output voltage and dimming feature make it an ideal solution for LED dimmable lighting in smart homes, schools, hospitals, universities, and commercial centers.

Working Principle of MP1494SGJ-Z

The MP1494SGJ-Z utilizes a buck-boost circuit, which is a type of switched-mode power converter. The buck-boost converter allows the input voltage to be either higher or lower than the output voltage, enabling it to be used for both step-up (boost) and step-down (buck) regulation. The device works by switching a high current MOSFET between a positive and a negative voltage level to create an alternating current (AC) waveform, which is then rectified and filtered to provide a DC output.

The output voltage of the MP1494SGJ-Z can be adjusted by varying the frequency of the switching waveform and the duty cycle. The device also features an adjustable dimming function, which allows it to vary the output current in order to reduce the level of light output. This is achieved by varying the on-time and/or off-time of the switching waveform.

Conclusion

The MP1494SGJ-Z is a high voltage DC DC switching regulator, specifically designed for LED applications. It has a wide adjustable output voltage range, an adjustable switching frequency, high efficiency, and a wide dimming range. This device is ideal for high powered LED lighting applications, LED TV backlight, architectural lighting, LED signs, and individual LED light source applications. It works by switching a high current MOSFET between a positive and negative voltage level to create an AC waveform, which can then be rectified and filtered to provide a DC output. The output voltage of the device can be adjusted by varying the frequency of the switching waveform, while the duty cycle can be used to vary its dimming level.
