Quality Control: Learn More
The Renesas Electronics Corporation ISL6558CR is a highly integrated multi-phase buck (step-down) DC-DC controller designed for efficient power delivery. This device offers up to four output phases, configurable for simultaneous operation or independent control to optimize transient response and reduce output voltage ripple. It features a wide switching frequency range from 80kHz to 1.5MHz, allowing for flexibility in component selection and board space optimization.
Key control features include Enable and Frequency Control for system management, along with a Power Good output for monitoring. The ISL6558CR supports a maximum duty cycle of 75% and operates with a supply voltage range of 4.75V to 5.25V. Its 20-QFN (5x5) package with an exposed pad facilitates efficient thermal management. This controller finds application in high-performance computing, server power, and telecommunications infrastructure where robust and efficient voltage regulation is critical.
