LM5041  
Cascaded PWM Controller  
General Description  
Features  
n Internal Start-up Bias Regulator  
The LM5041 PWM controller contains all of the features  
necessary to implement either current-fed or voltage-fed  
push-pull or bridge power converters. These “Cascaded”  
topologies are well suited for multiple output and higher  
power applications. The LM5041’s four control outputs in-  
clude: the buck stage controls (HD and LD) and the push-  
pull control outputs (PUSH and PULL). Push-pull outputs are  
driven at 50% nominal duty cycle at one half of the switching  
frequency of the buck stage and can be configured for either  
a guaranteed overlap time (for current-fed applications) or a  
guaranteed both-off time (for voltage-fed applications).  
Push-pull stage MOSFETs can be driven directly from the  
internal gate drivers while the buck stage requires an exter-  
nal driver such as the LM5102. The LM5041 includes a  
high-voltage start-up regulator that operates over a wide  
input range of 15V to 100V. The PWM controller is designed  
for high-speed capability including an oscillator frequency  
range up to 1 MHz and total propagation delays of less than  
100ns. Additional features include: line Under-Voltage Lock-  
out (UVLO), soft-start, an error amplifier, precision voltage  
reference, and thermal shutdown.
