The ISL6549CR-T is a dual-output voltage regulator designed for high-performance applications, providing both a synchronous rectified buck PWM controller and a linear regulator. It operates from a single 12V input supply, eliminating the need for a separate 5V supply. The device supports adjustable output voltages down to 0.8V and features a maximum static regulation tolerance of ±1% across line, load, and temperature variations. This regulator includes an integrated soft-start feature to control the power-up sequence and monitors both outputs for undervoltage conditions, shutting down the converters if necessary. The ISL6549CR-T is available in a compact 16 Ld 4x4 QFN package, making it suitable for applications such as processor and memory supplies, ASIC power supplies, and embedded systems. Its adjustable frequency ranges from 150kHz to 1MHz, allowing for flexibility in design while maintaining a small external component count.
