FDSL024RG

FDSL024RG is an advanced large module Synchronous Rectification Control dedicated chip developed by Fudan Macro according to the field characteristics and requirements of the power supply industry, which is used for the design scheme of AC-DC synchronous rectification circuit. This chip has the functions of power adjustment, temperature protection, short circuit protection, current limitation, etc. It can protect the power supply from over or under voltage and easily realize the module synchronization. This chip has the advantages of excellent performance, strong scalability and fast synchronous rectification speed.

FDSL024RG is widely used in various power supplies, automotive electronics, industrial control systems and other fields. Especially for high-power regulated switching power supplies, it is the most widely used, such as switching power supply, adapter, battery charger, inverter and other high power application projects.

The working principle of FDSL024RG is based on integrating the error amplifier, pulse signal generator and power electronics output stage together. Through the pulse signal generator, the analog reference voltage signal is transformed into a digital pulse signal, and then transmitted to the output power device to output the control current or voltage. The main function of the integrator is to compare the measured output voltage with the reference voltage, and then generate an error signal. Then, the error signal is amplified and processed by the error amplifier. Finally, the output power device is driven through the Pulse Signal Generator to adjust the output voltage and other parameters of the power supply.

FDSL024RG has excellent features and advantages compared with traditional power regulators. Its constant voltage mode can achieve 4% or less steady state error; The fast-response function of the constant voltage mode can reduce the maximum response time to 30us; In addition, the standby current is extremely low, and the power consumption is only 87mW.

With a flexible, powerful, and reliable FDSL024RG chip, a wide range of applications could be realized. With the continuous innovation of core technology and functional processing, FDSL024RG will bring longer product life and excellent performance to more products in the future.
