The Renesas Electronics Corporation ISL6558CRZA-T is a multiphase PWM (Pulse Width Modulation) DC-DC buck controller. This device is designed for high-performance step-down power conversion, featuring four output phases for improved current handling and transient response. It operates with a switching frequency range from 80kHz to 1.5MHz and supports a maximum duty cycle of 75%. The controller integrates key features such as Enable and Frequency Control, along with a Power Good output for system monitoring. Its input voltage range is 4.75V to 5.25V, making it suitable for applications requiring stable positive output voltages. The ISL6558CRZA-T is housed in a 20-QFN (5x5) package, designed for surface mounting. This component is commonly utilized in computing, server, and telecommunications power supply designs. The ISL6558CRZA-T is supplied in Tape & Reel (TR) packaging.
