Device description
The L6591 is a double-ended PWM controller specific for 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 dead-time inserted between the turn-off of one switch and the turn-on of the other one guarantees soft- switching and enables high-frequency operation.
