LM5041B 的特色
LM5041B 的說明
The LM5041B 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 LM5041B includes these four control outputs: 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 non-overlap time
(for voltage-fed applications). Push-pull stage
The differences between LM5041, LM5041A and LM5041B are as follows: In the LM5041A and the LM5041B version, the hiccup mode
over-current protection is not employed and the VCC bias regulator is not disabled by a low state at the SS pin. In the LM5041B
version, both the high and low side buck stage gate drivers are forced to a low state when the controller is disabled. In
the LM5041 and the LM5041B version, the buck stage controller is disabled by either a low state at the
