Product Summary

The LM5000-3MTC Enhanced Plastic High Voltage Switch Mode Regulator is a monolithic integrated circuit specifically designed and optimized for flyback, boost or forward power converter applications. The internal power switch is rated for a maximum of 80V, with a current limit set to 2A. Protecting the power switch are current limit and thermal shutdown circuits. The current mode control scheme provides excellent rejection of line transients and cycle-by-cycle current limiting. An external compensation pin and the built-in slope compensation allow the user to optimize the frequency compensation. Other distinctive features of LM5000-3MTC include softstart to reduce stresses during start-up and an external shutdown pin for remote ON/OFF control. The LM5000-3MTC is ideal for: (1)Flyback Regulator; (2)Forward Regulator; (3)Boost Regulator; (4)Distributed Power Converters; (5)Selected Military Applications; (6)Selected Avionics Applications.
