The LM5001 high-voltage switch-mode regulator features all of the functionsnecessary to implement efficient high-voltage Boost, Flyback, SEPIC and Forwardconverters, using few external components. This easy-to-use regulator integratesa 75-V NChannel MOSFET with a 1-A peak current limit. Current mode controlprovides inherently simple loop compensation and line-voltage feed-forward forsuperior rejection of input transients. The switching frequency is set with asingle resistor and is programmable up to 1.5 MHz. The oscillator can also besynchronized to an external clock. Additional protection features include:current limit, thermal shutdown, undervoltage lockout and remote shutdowncapability.
