Overview
LM5041 Cascaded PWM Controller August 2003 LM5041 Cascaded PWM Controller General Description 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 pushpull 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 tim...
