Power Management


Microsemi's high-performance analog/mixed-signal ICs provide high precision, ultra-fast regulation, high efficiency, and small footprint size for power management and power conversion applications. Microsemi's Hysteretic Control Step-Down Switching Regulators provide best in class transient performance. Our advanced Resonant Mode (LLC) Controllers ensure the lowest possible electromagnetic interference (EMI) with very high efficiency. Coming in 2014 is Microsemi's Smart E-Fuse device technology that protects the power management circuits against voltage spikes and surges, while controlling inrush currents, hot-plug, and crow bar events. Microsemi continues to innovate, with Power Management solutions for Commercial, Industrial, Military and Space applications.
