ISL6558 Datasheet (Intersil) - Multi-Purpose Precision Multi-Phase PWM Controller

ISL6558, Multi-Purpose Precision Multi-Phase PWM Controller

NOTE: Pin numbers refer to the SOIC package.

Check PINOUT diagrams for QFN pin numbers.

VCC (Pin 1) Supplies all the power necessary to operate the chip.

The IC starts to operate when the voltage on this pin exceeds the rising POR threshold and shuts down when the voltage on this pin drops below the

® Data Sheet February 2003 ISL6558 FN9027.4 Multi-Purpose Precision Multi-Phase PWM Controller With Optional Active Voltage Positioning The ISL6558 is a multi-phase PWM TM controller, which in combination with the HIP6601B, HIP6602B, HIP6603B, or ISL6605 companion gate drivers form a complete 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 converte
