S-8357B38UA-NIXT2U Application Field and Working Principle
PMIC (Power Management Integrated Circuit) - Voltage Regulators - DC DC Switching Controllers - S-8357B38UA-NIXT2U
The S-8357B38UA-NIXT2U is a switching power supply controller integrated circuit. It was developed to provide a low-cost, low-power solution for a wide range of switching power supply applications such as LED lighting, telecoms, computers, renewable energy conversion and other electronic products.
Applications of S-8357B38UA-NIXT2U:
- LED lighting
- Telecoms
- Computers
- Renewable energy conversion
- Other electronic products
In addition to its capability in DC-DC conversion, the S-8357B38UA-NIXT2U has many other features necessary to construct efficient, low-cost power supplies. Firstly, its internally-generated soft-start peak current limit provides an extremely fast start-up time and further improved efficiency of the power supply by reducing the total input power. Secondly, it provides a frequency modulation (FM) loop which helps to reduce EMI levels. Last but not least, the S-8357B38UA-NIXT2U also supports steady state operating temperature detection and automatic protection circuitry in cases of overload or short circuit.
The working principle of S-8357B38UA-NIXT2U can be divided into 6 parts. Firstly, the power supply circuit provides a DC supply voltage to the converter. Secondly, the controller regulates the PWM signal that controls the on/off state of the power switches. The third step is to apply current feedback for current limiting and overload protection. Then, the fourth step is to monitor and control the output voltage using a voltage feedback loop. Fifthly, the controller performs overvoltage and undervoltage protections. Last but not least, the sixth step is to reset the converter in cases of overload and over temperature protections.
In conclusion, the S-8357B38UA-NIXT2U is a low-cost, low-power switching power supply controller with many features necessary to construct efficient, low-cost power supplies. It can be used in a wide range of applications such as LED lighting, telecoms, computers and renewable energy conversion. Its working principle can be divided into 6 steps: power supply, PWM control, current feedback, voltage feedback, overvoltage/undervoltage protection, and reset.
