Product Overview

The LM5041MTC/NOPB is a Pulse Width Modulated (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 15 to 100V.
