The Renesas Electronics Corporation ISL6420BIRZ is a highly efficient, single-phase, synchronous buck DC-DC controller. This device is designed for step-down voltage conversion and features a 20-QFN (4x4) package with an exposed pad for enhanced thermal performance. The ISL6420BIRZ operates with a wide input voltage range from 5.6V to 28V and offers a selectable switching frequency from 100kHz up to 1.4MHz, allowing for optimization of component size and efficiency.
Key control features include Enable, Frequency Control, Phase Control, Power Good indication, and Soft Start for robust power sequencing. The controller supports a maximum duty cycle of 96% and integrates a synchronous rectifier for improved efficiency. This component is well-suited for applications in industrial power supplies, telecommunications equipment, and general-purpose power conversion where reliable step-down regulation is critical. The operating temperature range is -40°C to 85°C (TA).
