LM5001 High
Voltage Switch Mode Regulator
General 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 Volt N-Channel
MOSFET with a 1 Amp peak current limit.
Current mode control provides inherently simple loop compensation and line-
voltage feed-forward for superior rejection com of input transients.
The switching frequency is set with a single resistor and is programmable up to 1.
5MHz.
The oscillator can also be synchroniz...
