Working Principle
The S-8352D33MC-K8ST2U switch controller is a synchronous step-down DC-DC converter that employs switching transistors to regulate the energy flow of the circuit. The circuit consists of a switching transistor, an LDO regulator, and a voltage divider. When the input voltage is lower than the output voltage, the circuit turns off the MOSFET and the LDO regulator steps up the output voltage to the value set in the voltage divider.
When the input voltage is higher than the output voltage, the circuit turns on the MOMFET, allowing the synchronous rectifier to deliver power to the output voltage. The current in the synchronous rectifier is limited to the value set in the voltage divider. This allows the regulator to achieve high efficiency while limiting the current to a value set by the user.
Conclusion
The S-8352D33MC-K8ST2U switch controller has a range of features that make it ideal for a wide range of applications. it has a wide input voltage range, a high efficiency, low drop out voltage, and low quiescent current requirements, making it ideal for digital consumer products, wearable devices, mobile devices, gaming consoles, and motor control systems. Lastly, the switch controller’s working principle is based on a synchronous step-down DC-DC converter using MOSFETs, an LDO regulator, and a voltage divider, which allow it to achieve high efficiency while limiting the current to a value set by the user.
