SNVS484H – JANUARY 2007 – REVISED JULY 2015 LM5001x High-Voltage Switch-Mode Regulator
1 Features 3 Description The LM5001 high-voltage switch-mode regulator
features all of the functions necessary to implement
efficient high-voltage Boost, Flyback, SEPIC and
Forward converters, using few external components.
This easy-to-use regulator integrates a 75-V NChannel MOSFET with a 1-A peak current limit.
Current mode control provides inherently simple loop
compensation and line-voltage feed-forward for
superior rejection of input transients. The switching
frequency is set with a single resistor and is
programmable up to 1.5 MHz. The oscillator can also
be synchronized to an external clock. Additional
protection features include: current limit, thermal
shutdown, undervoltage lockout and remote
shutdown capability. 1 AEC-Q100 Qualified (TJ = –40°C to 125°C)
