Furthermore, the DC-DC switching controller is designed specifically for use in ground vehicles and its operation is guaranteed between -40°C and +125°C.
Working Principle
The MB39A135PFT-G-JN-ERE1 is a current-mode DC-DC switching controller. It is designed to provide a simple and accurate solution to current mode control applications. In order to regulate the output voltage, the switching controller uses PWM technology, which compares the output voltage with a reference voltage. The reference voltage is provided by the external components which permit regulation of the output voltage.
The DC-DC switching controller also monitors and protects the device from the risk of thermal overloading or from supplying an excessive current into the output. In order to protect itself from overheating, the device will automatically shut off in case of an overcurrent condition on the output. Hence, if an overload does occur, the device will automatically cut off the power supply, protecting the device from damage.
In other words, the reference voltage is compared with a ramp signal generated by the MB39A135PFT-G-JN-ERE1 that signals when too much current is flowing through the output. When the voltage generated by the ramp signal reaches the reference voltage, the device will shut off the power supply.
Conclusion
The MB39A135PFT-G-JN-ERE1 is a high-current DC-DC switching controller integrated circuit that is used in a variety of applications. It is specially designed for voltage regulation and current protection, providing reliable and accurate performance. Moreover, the device offers Surge IP3, over-voltage/thermal protection and current limiting, making it an ideal choice for builds that require these functions. Additionally, it is suitable for switching frequency control and its operation is guaranteed between -40°C and +125°C. The MB39A135PFT-G-JN-ERE1 is a great choice for applications requiring reliable performance and precision.
