LM5046MH/NOPB +BOM

Advanced voltage regulator for precision power control applications

LM5046MH/NOPB Information

Allgemeine Beschreibung

Featuring advanced functionality such as cycle-by-cycle current limiting, hiccup mode restart, and programmable soft-start, the LM5046MH/NOPB offers a comprehensive solution for power management requirements. The inclusion of a 2-MHz capable oscillator with synchronization capability and thermal shutdown further enhances the controller's reliability and performance. With the ability to program dead-time for zero-volt switching of primary FETs and control secondary-side synchronous rectifier MOSFETs, this controller is a versatile and efficient choice for demanding power conversion applications
