PWM Controller for Asymmetrical Half-Bridge Flyback Converters

The RT7795M is a specialized controller designed for Asymmetrical Half-Bridge (AHB) flyback converters, commonly employed in various applications. It is capable of delivering an output power of 300W and features a versatile output voltage range from 5V to 48V, making it particularly well-suited for USB-PD EPR (Extended Power Range) applications.To ensure peak efficiency, the RT7795M utilizes a resonant mode of operation for the AHB, effectively minimizing power losses for both the AHB and the secondary-side synchronous rectifier. Furthermore, the RT7795M addresses potential audio noise issues through a proprietary jitter approach that disperses the energy and frequency of the noise.In addition to its performance features, the RT7795M includes comprehensive protection functionality, ensuring the safety and reliability of the power supply.The RT7795M collaborates with the synchronous rectification controller RT7220E to offer a comprehensive power solution, maximizing efficiency.For USB-PD or programmable power supply applications, pairing the RT7795M with the secondary-side controller RT7209 ensures a robust and secure design, safeguarding both the power supply and any connected systems.The recommended junction temperature range is from -40°C to 125°C, while the ambient temperature range is from -40°C to 85°C.
