Multi-Purpose Precision Multi-Phase PWM Controller With Optional Active Voltage Positioning
The ISL6558 is a multi-phase PWM TM controller, which in bination with the HIP6601B, HIP6602B, HIP6603B, or ISL6605 panion gate drivers form a plete solution for high-current, high slew-rate applications. The ISL6558 regulates output voltage, balances load currents and provides protective functions for two to four synchronous rectified buck converter channels.
A novel approach to current sensing is used to reduce overall solution cost and improve efficiency. The voltage developed across the lower MOSFET during conduction is sampled and fed...
