L6591

Current mode PWM controller for Asymmetrical Half Bridge converter topology

ECCN USEAR99
ECCN EUNEC
Packing TypeTube
RoHs compliantEcopack2
GradeIndustrial
Package NameSO-16

The L6591 is a double-ended PWM controller specific to the soft-switched half bridge topology. It provides complementary PWM control, where the high-side switch is driven ON for a duty cycle D and the low-side switch for a duty cycle 1-D, with D < 50%. An externally programmable deadtime...
