Fonctionnalités et applications
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.
Features:
- Complementary PWM control for soft-switched half-bridge with programmable dead-time
- Up to 500 kHz operating frequency
- On-board high-voltage start-up
- Advanced light load management
- Adaptive UVLO
- Pulse-by-pulse OCP
- OLP (latched or autorestart)
- Transformer saturation detection
- Interface with PFC controller
- Latched disable input
- Input for power-on sequencing or brownout protection
- Programmable soft-start
- 4% precision external reference
- 600 V-rail compatible high-side gate driver with integrated bootstrap diode and high dV/dt
- immunity
- SO16N package
Applications:
- High power AC-DC adapter/charger
- Desktop PC, entry-level server
- Telecom SMPS
