Working Principle

The MB39A136PFT-G-JN-ERE1 is a synchronous buck controller which uses a technique called pulse-width modulation (PWM) control to regulate the output voltage. When the voltage input is given to the controller, it will set the output voltage according to the voltage sensing circuit input. The pulse-width modulation control is used to convert the input voltage to an output voltage of higher or lower potential, which is then regulated by the controller. This allows the output voltage to be regulated precisely, while also increasing efficiency.

The MB39A136PFT-G-JN-ERE1 also has an advanced protection system which prevents the device from exceeding its limits. It is able to detect overcurrent, over voltage and short circuit events, and will shut down immediately in the event of any of these events. This protection system helps ensure safe operation of the device and prevents damage to the electronic systems in which it is used.

The MB39A136PFT-G-JN-ERE1 is a DC-DC switching controller from the Voltage Regulators PMIC family. It is suitable for a wide range of industrial and consumer applications due to its high efficiency and advanced protection system. It uses pulse-width modulation control to regulate the output voltage and its advanced protection system helps prevent damage to the system.
