Working Principle of NJU7261U50

NJU7261U50 is a dual-channel working synchronous buck converter. It works by controlling the duty cycle of the switch and thus regulating the voltage output. The following steps describe the working principle of NJU7261U50:

• Step 1: The input voltage is applied to the switching regulator.
• Step 2: The switching regulator then converts the input voltage to a lower output voltage, based on the duty cycle of the switch.
• Step 3: The output of the switching regulator is regulated by a feedback loop. The feedback voltage is compared to the reference voltage, and the error is used to adjust the duty cycle of the switch.
• Step 4: The switching regulator adjusts the output voltage and controls the current, thus providing a stable output voltage.

NJU7261U50 is a highly integrated solution that requires a few external components to regulate the current and maintain the output voltage. It also comes with a built-in overcurrent and overtemperature protection, further increasing the safety and reliability of the output voltage.
