Its dual gate drive voltage inputs optimize gate driver 15 A no-load quiescent current with the output voltage in regulation extends operating run time in battery powered systems. Low ripple Burst Mode operation enables high efficiency at very light loads while maintaining low output voltage ripple. The LT8711's fixed switching frequency can be set from 100kHz to 750kHz or can be synchronized to an external additional features include 100% duty cycle capability when in buck mode, a topology selection pin and adjustable soft-start. LT8711 is available in the 20-lead TSSOP and 20-lead 3mm 4mm QFN registered trademarks and trademarks are the property of their respective owners.
