FEATURES  
DESCRIPTION  
The LM5000 is  
a monolithic integrated circuit  
2
80V Internal Switch  
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  
include softstart to reduce stresses during start-up  
and an external shutdown pin for remote ON/OFF  
control. There are two operating frequency ranges  
available. The LM5000-3 is pin selectable for either  
300kHz (FS Grounded) or 700kHz (FS Open). The  
LM5000-6 is pin selectable for either 600kHz (FS  
Grounded) or 1.3MHz (FS Open). The device is  
available in a low profile 16-lead TSSOP package or  
a thermally enhanced 16-lead WSON package.  
Operating Input Voltage Range of 3.1V to 40V
