The MPM3608SJ is one of the latest AC/DC converters made by Power Integrations, Inc., a leading provider of DC/DC converters, AC/DC power supplies, and integrated power supplies. This series of converter is designed for automotive applications, including power management systems and lighting systems. It offers high efficiency, low power consumption, and low cost.

The MPM3608SJ is designed to convert a nominal input voltage of 400-1000V AC to output voltages ranging from 3.3V to 24V DC. Its wide input range allows it to be used in a wide variety of applications, ranging from commercial vehicles to industrial and medical equipment. It also features a low total harmonic distortion rate of less than 10%. This ensures reliable and efficient power delivery.

The converter features a highly efficient power converter topology, with an efficiency rating that exceeds 85%. This power converter topology simplifies system designs, and also ensures that the converter will dissipate very little heat during operation. The converter is also designed with a dynamic current sharing feature, which allows multiple converters to be used in parallel for increased power output.

The MPM3608SJ also features advanced protection circuits that provide short-circuit, over-voltage, over-temperature, and over-current protection. The converter has an adjustable output voltage, allowing the user to easily adjust the output voltage to match the needs of the application. Its wide operating temperature range, from -40°C to +125°C, ensures it can withstand the extreme temperatures encountered in automotive applications.

The primary components of the MPM3608SJ converter are two main power transistors (MOSFETs), an inductor, an optocoupler, and a resistor. The two main power transistors control the current flow through the inductor, which is used to store energy. The optocoupler is used to provide isolation and to sense the current and voltage of the output. The resistor provides current sensing and protection.

The MOSFETs are controlled by a digital signal processor. The digital signal processor is programmed to periodically sample the input and output voltages, and adjust the duty cycle of the MOSFETs accordingly. This is known as Pulse Width Modulation (PWM), and it ensures that the output voltage remains in the desired range. This reduces power loss and ensures a stable output voltage over a wide range of load conditions.

The MPM3608SJ AC/DC converter series is designed for a variety of automotive applications, such as power management systems, lighting systems, and audio systems. It features high efficiency, low power consumption, and advanced protection circuits, making it an ideal choice for automotive applications. Its adjustable output voltage, wide operating temperature range, and low total harmonic distortion rate make it a reliable and cost-effective choice for a wide range of applications.
