DC DC Switching Controllers datasheet and documents for ISL6558CB

ISL6558CB

DC DC Switching Controllers Overview

The ISL6558CB is a multi-purpose precision multiphase PWM controller designed for synchronous rectified buck converter applications. It supports two to four phases and regulates output voltage while balancing load currents. The device operates with a supply voltage range of 4.75V to 5.25V and features a switchable frequency from 80kHz to 1.5MHz. It offers a maximum duty cycle of 75% and includes protective functions. The component is housed in a 16-SOIC package and operates within a temperature range of 0°C to 70°C.

DC DC Switching Controllers Feature Summary

Multi-phase PWM control for two to four synchronous buck channels
Active voltage positioning capability for improved transient response
Integrated protection mechanisms including over-current and thermal shutdown

DC DC Switching Controllers Applications

High-performance microprocessor core voltage regulation
Server and workstation power distribution networks
Telecommunications equipment power supplies

DC DC Switching Controllers Procurement Notes

Verify the specific suffix (e.g., CB vs CRZA) against the required package type, as variants exist in SOIC and QFN formats. Confirm RoHS compliance status, as some listings indicate non-compliance. Check lifecycle status carefully, as this part may be obsolete or discontinued depending on the manufacturing date code. Ensure gate driver compatibility with HIP6601B/6602B/6603B or ISL6605 if not integrated.

DC DC Switching Controllers Selection Notes

Select this controller when designing multi-phase buck converters requiring precise current sharing and fast transient response. It is suitable for applications needing adjustable switching frequencies up to 1.5MHz. Consider the 16-SOIC package constraints for PCB layout. Verify that the companion gate drivers match the selected phase count and voltage requirements for the target application.

DC DC Switching Controllers Part Context

The ISL6558 belongs to Intersil's Endura family of power management ICs, widely used in computing and telecom sectors. It complements companion gate drivers like the HIP6602B to form complete power stages. The series emphasizes precision and reliability for critical load points in digital systems.
