Working Principle

The S-8358H32MC-NURT2U is a type of DC DC Switching Controller. This device regulates the voltage to the load using a buck-boost topology. A buck-boost converter is an electrical circuit that converts a varying input voltage into a constant output voltage. This is accomplished by using a combination of buck and boost switching modes. The output of the converter is adjusted by the duty cycle of the switches. This is done by controlling the on time and off time of the switches.

The S-8358H32MC-NURT2U operates in a pulse width modulation (PWM) mode. The PWM mode allows for precise control of the output voltage. The PWM signal is generated by a controller IC and is used to drive a power MOSFET to switch the power from the input to the output. The MOSFET is used to regulate the current and the voltage at the output.

The S-8358H32MC-NURT2U also has an adjustable current limit and adjustable input voltage range. The maximum output current is limited by setting the adjustment wiring. This ensures that the system does not draw more current than it can handle. The input voltage range is adjustable, allowing the system to regulate the output voltage and current over a wide range of input voltages.
