CD5041
CD5041 is PWM Controller manufactured by CYT.
Description
The CD5041 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 CD5041’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).
