The LT3798EMSE#PBF is an isolated flyback controller designed for offline applications. It integrates active power factor correction (PFC) and eliminates the need for an opto-coupler for output voltage feedback, enabling single-stage conversion.
This controller supports constant-current and constant-voltage regulation with typical accuracy of ±5%. It operates within an input voltage range of 10V to 38V and a frequency range of 500Hz to 150kHz. The device is designed for efficiencies higher than 86% at output power levels up to 100W.
Key features include Energy Star compliance with less than 0.5W no-load operation. The LT3798EMSE#PBF is housed in a thermally enhanced 16-lead MSOP package and is suitable for surface mount applications. Its operating temperature range is -40°C to 125°C.
Applications include offline 5W to 100W+ power supplies, high DC input isolated applications, and offline bus converters with 12V, 24V, or 48V outputs.
