L6591 Product details

Description
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 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-switche half bridge with programmable deadtime
■ Up to 500 kHz operating frequency
■ Onboard high-voltage startup
■ 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
