The SM72485SDE/NOPB is a DC/DC switching regulator designed specifically for mobile phones that require low voltage power supply and other personal mobile devices. It is classified under the PMIC (Power Management IC) Voltage Regulators – DC DC Switching Regulators family. Its features and applications include:
Data line transformer applications: The SM72485SDE/NOPB is capable of delivering high quality data line signals with minimal distortion, thus making it ideal for data line transformer applications.
Low Voltage DC/DC conversion: This IC can provide step down conversion from a higher voltage to a lower voltage with a minimum of power loss. The device operates with a Duty Cycle Accuracy of 2%, minimizing component count and power loss risks.
Fault and disable FETs: This highly efficient IC provides automatic shutdown in the case of a fault, thus preventing further damage. The device is also capable of disabling the FETs, eliminating current load and improving the overall efficiency of the circuit.
Digital/Analog regulated voltage: The SM72485SDE/NOPB features both digital and analog voltage regulation. The device provides precise voltage regulation, ideal for mobile phones and other personal mobile devices that require accurate voltage regulation.
Scalable Versatility: This device can be configured to meet a variety of customer specifications. The device features high frequency switching, synchronization with other devices, precise current limit, and over temperature protection.
Working Principle: The working principle of the SM72485SDE/NOPB is based on a buck converter – which is a type of DC-DC converter circuit – and a voltage regulator controller. The buck converter consists of an inductor, a switch, a diode and a capacitor. The switch is turned on or off by the controller, depending on the input voltage and the output voltage. The inductor builds magnetic energy when the switch is in the closed position, and the diode prevents this energy from flowing back into the power source when the switch is opened. The capacitor stores energy and ensures the output voltage is maintained at the desired level. The voltage regulator controller is responsible for regulating the output voltage by controlling the duty cycle of the switch.
Overall, the SM72485SDE/NOPB is a high performance DC/DC switching regulator designed specially for personal mobile devices. It is highly efficient and versatile, offering scalability and a range of features. Its low-voltage operation and built-in protection makes it an ideal choice for applications such as mobile phones and other personal mobile devices.
