Renesas Electronics Corporation PMIC - PMIC - Voltage Regulators - DCDC Switching Controllers - ISL6553CB-T ISL6553CB-T

The ISL6553CB-T is a multi-phase PWM controller IC designed for precision voltage regulation in advanced microprocessor applications. It supports programmable VID codes ranging from 1.05V to 1.825V with a system accuracy of ±1%, allowing for flexible voltage adjustments. The controller features a fast transient response and includes droop compensation, which can be easily set with a single resistor to minimize voltage overshoot or undershoot. This IC is equipped with a power good (PGOOD) monitor that indicates when the CORE voltage is within specified limits, and it incorporates over-voltage and under-voltage protection mechanisms to safeguard the microprocessor. Additionally, it offers over-current protection that limits the output current to 41% of the programmed trip value, enhancing the reliability of the power system. The ISL6553CB-T operates with a high ripple frequency, which improves efficiency by allowing the use of smaller, lower-cost components. It is available in a 16-lead SOIC package and is suitable for applications requiring robust power management solutions.
