LM5020  
100V Current Mode PWM Controller  
General Description  
Features  
n Internal Start-up Bias Regulator  
n Error Amplifier  
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 in-  
herent 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. Addi-  
tional 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  
MSOP-10 and LLP-10 packages.  
n Precision Voltage Reference  
n Programmable Softstart  
n 1A Peak Gate Driver  
n Maximum Duty Cycle Limiting (80% for LM5020-1 or  
50% for LM5020-2)  
n Programmable Line Under Voltage Lockout (UVLO) with  
Adjustable Hysteresis  
n Cycle-by-Cycle Over-Current Protection  
n Slope Compensation (LM5020-1)  
n Programmable Oscillator Frequency with  
Synchronization Capability  
n Current Sense Leading Edge Blanking  
n Thermal Shutdown Protection  
Packages  
n MSOP-10  
n LLP-10 (4 mm x 4 mm)
