The FSDL0365RNB is a power supply IC that is designed for switch mode power supplies and applications such as AC/DC conversion, offline switchers and auxiliary supplies. This article will provide an overview of the FSDL0365RNB – its applications, features and working principles.

Applications of the FSDL0365RNB

The FSDL0365RNB IC can be used for AC/DC conversion, offline switchers and for auxiliary supplies. As an AC/DC converter, it can be used to efficiently convert mains AC power to output DC power. As an offline switcher, it can be used to provide a cost-effective and high-efficiency alternative to linear power supplies. And as an auxiliary supply, it can be used to run auxiliary motors, displays, and other components.

Features of the FSDL0365RNB

The FSDL0365RNB offers many features that make it ideal for use in power conversion and other power supply applications. It offers wide operating frequency range, low stand-by power, high efficiency, compact size, and thermal protection. Additionally, it features integrated synchronous rectifiers for enhanced efficiency, and a low pin count for improved reliability.

Working Principles of the FSDL0365RNB

The FSDL0365RNB works by converting mains AC power to DC output voltage. It does this through two main components – the switch mode power supply and the Pulse Width Modulator (PWM). The PWM acts as the control element, allowing the current-controlled switch mode power supply to regulate the output voltage. The device is optimized to operate in a fixed-frequency Vcc/Pulse-width modulation (stock PWM) mode.

The control logic integrated into the FSDL0365RNB ensures optimal performance. It offers a high switching frequency of up to 200 kHz, to ensure precise voltage regulation, and it has over-current, short-circuit, and over-temperature protection. In addition, its high frequency allows it to switch with very low losses. The device is also highly efficient, as it can reach up to 99% efficiency depending on the load condition.

Conclusion

The FSDL0365RNB is a versatile IC that can be used for a variety of applications. Its features, such as wide operating frequency range, low stand-by power, high efficiency, and thermal protection, make it ideal for use in power conversion and other power supply applications. Additionally, its integrated synchronous rectifiers and low pin count help to ensure reliability. As a result, the FSDL0365RNB is an excellent solution for AC/DC conversion, offline switchers and auxiliary supplies.
