DC-DC Converters are used in many applications, such as power converters, audio amplifiers, industrial equipment, and automotive electronics. A DC-DC converter is a type of electronic circuit that uses switching technology to convert a source of DC power from one voltage level to another. The JSM1024S15 is one such device that functions at up to 100 kHz and is intended for a wide range of DC-DC applications.

Applications of JSM1024S15

The primary application of the JSM1024S15 is its ability to provide a regulated output voltage for dc-to-dc conversion. This makes the device suitable for power conversion in numerous applications, such as automotive electronics, battery chargers, switch-mode power supplies, and other non-isolated applications. Additionally, the device is suitable for industrial control, video and telecom systems, automotive charging systems, white goods, and more.

The device operates with a switching frequency of up to 100 kHz and other features that make it suitable for high frequency applications such as motor drives, power audio and illuminations, and LED lighting. It also offers protection features that include a temperature monitor and short-circuit protection. The device is available in a range of packages, including a compact SIP package.

Working Principle of JSM1024S15

The JSM1024S15 DC-DC converter works by using pulse width modulation (PWM) to control the output voltage regulation within a certain range. This is achieved by using two power MOSFETs that act as a switch between two sources of power, the input voltage and the output voltage. By controlling the PWM, the device is able to switch on and off the power MOSFETs with varying pulse widths, thereby converting the output voltage to the desired level.

The device has two “error” amplifiers that sense the difference between the output voltage and a reference voltage. When there is a difference in voltage, the output voltage is either increased or decreased controllably. One of the error amplifiers operates in a linear mode and the other operates in a pulse width modulation mode. This enables a wide range of output voltage compliance and more precise control of the output voltage.

The JSM1024S15 also includes a thermal shutdown monitor, which monitors the junction temperature of the power MOSFETs and keeps it within a certain safe level. If the device reaches a temperature that exceeds the safe level, the device will automatically shut down, protecting the DC-DC converter from damage due to high temperatures.

The device also offers short-circuit protection to prevent damage due to accidental wiring errors or misconnection of the wiring. If the device is accidentally connected to a short-circuit condition, the DC-DC converter will automatically shut down, thereby protecting the associated components.

Conclusion

The JSM1024S15DC-DC converter is a very efficient and reliable device suitable for a wide range of DC-DC applications. It offers high frequency operation up to 100 kHz, temperature monitoring capability, and short-circuit protection. Its ability to provide a regulated output voltage coupled with its numerous protection features makes it an ideal choice for a wide range of applications.
