Current Mode Control  
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 include: 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 specified overlap time (for  
current-fed applications) or a specified 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 external  
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 Lockout (UVLO),  
soft-start, an error amplifier, precision voltage  
reference, and thermal shutdown.
