Description
General part information
LT8711 Series
The LT8711 is a multi-topology current mode PWM controller that can easily be configured as a synchronous buck, boost, SEPIC, ZETA or as a nonsynchronous buck-boost converter. Its dual gate drive voltage inputs optimize gate driver efficiency.The 15µA 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 clock.The 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 packages.ApplicationsGeneral Purpose DC/DC ConversionAutomotive SystemsIndustrial SuppliesSolar Panel Power Converter
