DC DC Converters

DC-DC converters are power converters that convert one DC voltage level to another. The PJT014A0X3-SRZ model is an efficient and cost-effective solution. It is a DC-DC converter designed to convert DC input voltage from a range of 8-40V to a DC output voltage of 5V. It is a high power, wide input range and high efficiency step-down module. With its built-in active current-limiting and over temperature protections, it ensures stability and safety when powering an end device.

Applications of the PJT014A0X3-SRZ

The PJT014A0X3-SRZ is suitable for a variety of applications, including factory automation, consumer electronics, automotive infotainment systems, networks and communications, and solar power systems. Its wide input voltage range makes it suitable for a wide range of input voltages, from 8V - 40V, making it an ideal choice for applications with varying input voltages. Its competitive pricing makes it an attractive choice for cost-sensitive applications.

Due to its high efficiency of up to 93%, the PJT014A0X3-SRZ is perfect for applications in which power is scarce, including embedded systems, portable electronics, and motion-sensing applications such as in-vehicle cameras, as it requires less input power to achieve the same load output. Its small package size also makes it ideal for tight space applications.

It is also well suited for applications that require overvoltage and overcurrent protection. Its built-in active current and temperature-limiting protections ensure stability and safety during operation.

Working Principle of the PJT014A0X3-SRZ

The PJT014A0X3-SRZ is a buck-type DC-DC converter, which uses a switch to control the output voltage. The switch is used to switch between two sources of potential low-voltage and high-voltage sources of DC power. When the switch is on, it will draw power from the high-voltage source and when the switch is off, it will draw power from the low-voltage source.

The PJT014A0X3-SRZ is an adjustable version of the buck converter, and it uses a Feedback pin to adjust the output voltage to the required 5V level. The Feedback pin is connected to the load and measures its voltage. This voltage is then compared to the Internal Reference Voltage. When the load voltage is below the reference voltage, the switch is kept on for a longer time, and when the load voltage is above the reference voltage, the switch is kept off for a longer time. This ensures that the output voltage remains steady at the reference voltage.

The PJT014A0X3-SRZ also incorporates a protection scheme which allows for overvoltage and overcurrent protection in the event of an over-voltage or over-current condition. It also provides current limiting and thermal shutdown protection to ensure operation within safe limits.

Conclusion

The PJT014A0X3-SRZ is a buck-type DC-DC converter with a wide input voltage range of 8-40V and a output voltage of 5V. It is a highly efficient and cost-effective solution for a wide range of applications. Its built-in active current and temperature-limiting protections ensure the stability and safety of the end product. Furthermore, its small package size makes it well suited for applications with limited space.
