Renesas Electronics Corporation Voltage Regulators - Linear + Switching ISL6528CB

The ISL6528CB is a dual-output voltage regulator designed for high-performance applications such as graphics cards and embedded processors. It features a standard buck PWM controller and a linear power controller, allowing it to provide two regulated output voltages simultaneously. The device operates at a constant frequency of 600kHz and offers a maximum static regulation tolerance of ±2% across various conditions, including line, load, and temperature variations. The output voltage range is adjustable from 0.8V to 3.3V using external resistors, making it versatile for different applications. An integrated soft-start feature ensures that both outputs reach regulation smoothly, while undervoltage monitoring protects against faults by shutting down the regulators if the output drops below 52.5% of the reference voltage. The ISL6528CB is packaged in an 8-lead SOIC format and is suitable for applications requiring both high current and lower current supplies, such as GPU and memory power supplies.
