Renesas Electronics Corporation Special Purpose Regulators ISL6369CRZ

The ISL6369CRZ is a hybrid digital dual PWM controller designed for Intel VR12/IMVP7 compliance, featuring a 6-phase PWM for microprocessor core or memory voltage regulation and a single-phase PWM for peripheral voltage regulation. It utilizes Intersil's Enhanced Active Pulse Positioning (EAPP) modulation scheme, which enhances transient response and reduces the number of required output capacitors. This controller supports SMBus, PMBus, and I2C interfaces, allowing for programmable functions and telemetry, while eliminating the need for non-volatile memory and firmware. It includes features such as auto phase shedding for improved efficiency in light load conditions, dynamic VID compensation, and precise current sensing for load-line programming and overcurrent protection. The ISL6369CRZ also offers dual thermal monitoring, independent oscillators for each phase, and the capability to start up into pre-charged loads. Its design aims to optimize performance and efficiency across various operating conditions, making it suitable for applications requiring high flexibility and reliability in voltage regulation.
