Additional Details

The SC1097D1-TL utilizes Power Integrations' innovative FluxLink™ technology for accurate secondary-side control without an optocoupler. It operates in continuous conduction mode (CCM) to achieve high efficiency and low EMI. The device incorporates a comprehensive set of protection features, including overvoltage protection (OVP), undervoltage protection (UVP), short-circuit protection (SCP), and over-temperature protection (OTP). The frequency jittering feature significantly reduces EMI emissions, simplifying compliance with regulatory standards. The integrated 725 V MOSFET provides excellent ruggedness and reliability, making the SC1097D1-TL suitable for demanding applications. The accurate CV/CC regulation ensures stable output voltage and current, even under varying load conditions. The device is available in a compact SO-7 package. External components, such as input and output capacitors and a transformer, are required for complete power supply implementation. The SC1097D1-TL is a robust and cost-effective solution for a wide range of low-power applications.
