Renesas Electronics Corporation Special Purpose Regulators ISL6227IRZ-T

The ISL6227IRZ-T is a dual PWM controller designed for high-efficiency voltage regulation, particularly suited for DDR memory applications. It supports output voltage regulation in the range of 0.9V to 5.5V and operates from an input voltage range of 5V to 28V. The device features a complete DDR memory power solution with VTT tracking capabilities, allowing for precise voltage management in memory systems. This controller offers flexible PWM or HYS Plus PWM mode selection, enhancing efficiency at light loads through hysteretic diode emulation. It includes built-in protections such as undervoltage lockout, overvoltage, overcurrent, and power-good signals for both output channels. The ISL6227IRZ-T is packaged in a 28-lead QFN format and is RoHS compliant, making it suitable for various applications including notebook PCs, tablet devices, and portable instruments. Its excellent dynamic response and current mode control make it a reliable choice for engineers seeking efficient power management solutions.
