DESCRIPTION  
The LM5020 high voltage pulse-width-modulation  
(PWM) controller contains all of the features needed  
to implement single ended primary power converter  
topologies. Output voltage regulation is based on  
current-mode control, which eases the design of loop  
compensation while providing inherent line feed-  
forward. The LM5020 includes a high-voltage start-up  
regulator that operates over a wide input range up to  
100V. The PWM controller is designed for high speed  
capability including an oscillator frequency range to  
1MHz and total propagation delays less than 100ns.  
Additional features include an error amplifier,  
precision reference, line under-voltage lockout, cycle-  
by-cycle current limit, slope compensation, softstart,  
oscillator synchronization capability and thermal  
shutdown. The controller is available in both VSSOP-  
10 and WSON-10 packages.  
Maximum Duty Cycle Limiting (80% for  
LM5020-1 or 50% for LM5020-2)  
Programmable Line Under Voltage Lockout  
(UVLO) with Adjustable Hysteresis  
Cycle-by-Cycle Over-Current Protection  
Slope Compensation (LM5020-1)

Synchronization Capability
