The LT3798EMSE#PBF is an isolated flyback controller designed for power factor correction (PFC) applications, capable of achieving a power factor greater than 0.97. It operates within a wide input voltage range of 10V to 38V and supports output power levels from 5W to over 100W. The device features active PFC without the need for an opto-coupler, ensuring low harmonic distortion and compliance with energy efficiency standards such as Energy Star, with no-load operation consuming less than 0.5W. This controller provides constant-voltage and constant-current regulation with an accuracy of ¬±5% typical. It is housed in a thermally enhanced 16-lead MSOP package, suitable for high DC input applications. The LT3798 is designed to operate in critical conduction mode (CRM) and discontinuous conduction mode (DCM), making it versatile for various offline applications, including bus converters with 12V, 24V, or 48V outputs. The operating temperature range is from -40¬8C to 125¬8C, ensuring reliability in diverse environments.
