描述
The ISL6549 provides the power control and protection for two output voltages in high-performance applications. The dual-output controller drives two N-Channel MOSFETs in a synchronous rectified buck converter topology and one N-Channel MOSFET in a linear configuration. The controller is ideal for applications where regulation of both the processing unit and memory supplies is required. The synchronous rectified buck converter incorporates simple, single feedback loop, voltage-mode control with fast transient response. Both the switching regulator and linear regulator provide a maximum static regulation tolerance of ±1% over line, load, and temperature ranges. Each output is user-adjustable by means of external resistors. An integrated soft-start feature brings both supplies into regulation in a controlled manner. Each output is monitored via the FB pins for undervoltage events. If either output drops below 75% of the nominal output level, both converters are shut off and go into retry mode. The ISL6549 is available in a 14 Ld SOIC package, 16 Ld QSOP, or 16 Ld 4x4 QFN packages.
