LM5002  
High Voltage Switch Mode Regulator  
General Description  
Features  
The LM5002 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 0.5 Amp peak current  
limit. Current mode control provides inherently simple loop  
compensation and line-voltage feed-forward for superior re-  
jection of input transients. The switching frequency is set with  
a single resistor and is programmable up to 1.5MHz. The os-  
cillator can also be synchronized to an external clock. Addi-  
tional protection features include: current limit, thermal  
shutdown, under-voltage lockout and remote shutdown ca-  
pability. The device is available in both SO-8 and LLP-8  
packages.  
Integrated 75 volt N-Channel MOSFET  
Ultra-wide input voltage range from 3.1V to 75V  
Integrated high voltage bias regulator  
Adjustable output voltage  
1.5% output voltage accuracy  
Current mode control with selectable compensation  
Wide bandwidth error amplifier  
Integrated current sensing and limiting  
Integrated slope compensation  
85% maximum duty cycle limit  
Single resistor oscillator programming  
Oscillator synchronization capability  
Enable / Undervoltage Lockout (UVLO) pin  
Thermal shutdown
