The JSM1048D15 is a DC DC converter module with ultra wide 4:1 input voltage range of 9V - 36V and dual regulated outputs. It comes with single current mode buck converter and dual current mode PWM buck converters, allowing it to convert high 40A current from higher voltage to system power supply quickly and efficiently. It is often used as point-of-load converter, and is suitable for many applications such as telecom, automotive and aerospace. And it can also provide good performance for industrial and commercial system.

The JSM1048D15 is equipped with advanced synchronous rectification technology, which reduces parts count and EMI concerns. It also offers an additional level of protection to system components from over voltage, over current and over temperature. The wide input voltage range and pin-compatible current mode PWM buck converters make the DC-DC converter module compatible with a wide range of applications. The module supports an operating temperature range of -40℃ ~ 85℃.

Working Principle: The JSM1048D15 DC-DC converter module operates by means of two different types of buck converters. The single current mode buck converter has an input voltage range of 4.5V to 36V and is capable of providing an output voltage of 2.5V to 19.5V. The dual current mode PWM buck converters have an input voltage range of 9V to 36V and are capable of providing an output voltage of 0.9V to 12V. Both converters switch at a frequency of 300KHz.

The single current mode buck converter is a voltage regulator that converts the incoming DC voltage from the system into a regulated DC voltage. It does this by transferring energy from the input voltage to the output voltage through an internal switch, converting excess energy into heat. As the input voltage increases, the output voltage holds steady and reduces the energy lost in the conversion process.

The dual current mode PWM buck converters are slightly different, they are able to control the voltage delivered to the system using Pulse Width Modulation (PWM). These converters use pulses of varying width to control the amount of voltage supplied to the system. As the input voltage increases, the PWM converters can keep the output voltage within its operating range.

The JSM1048D15 module also features an additional level of protection, namely over voltage, over current and over temperature protection. The module is also equipped with an advanced synchronous rectification technology which reduces the parts count and EMI concerns providing a more efficient and reliable solution.

In conclusion, the JSM1048D15 DC-DC converter module is an excellent choice for applications requiring a wide input voltage range and dual output capability. It offers superior efficiency due to its synchronous rectification technology and additional protection features, as well as a wide operating temperature range. Whether it\'s used in telecom, automotive, aerospace or industrial applications, the JSM1048D15 DC-DC converter module will provide reliable and efficient power conversion.
