Product Summary
The L6591TR is a double-ended PWM controller for ZVS half-bridge. The L6591TR 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. The applications of the L6591TR include: High power AC-DC adapter/charger, Desktop PC, entry-level server, Telecom SMPS.
