OverviewMicrosemi'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.
The LX9610 is a 22V, 12A Power Module designed for step down point of load applications. This device includes a voltage mode synchronous controller including the compensation network, internal power MOSFETs and the output inductor all in a 15mm x 15mm QFN package.
Engineering Samples Available Now! The LX8233 is a fast acting bi-directional E-Fuse switch designed both to protect circuitry connected to its output (VOUT) from transient input voltage surges on its input (VCC), and to protect VCC from overload current events coming from the load on VOUT.
The LX7180A is a 4A step-down regulator with integrated MOSFETs placed in a space saving QFN12 2mm x 2mm package for today’s mobile devices.
The LX7302 is a single phase step down DC-DC controller IC designed to drive a high side N-channel MOSFET and a low side N-channel synchronous rectifier.
