FEATURES  
DESCRIPTION  
The LM5041A 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  
LM5041A’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 an overlap time (for current-fed  
applications) or a 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 LM5041A 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.
