Microchip’s highly integrated power modules contain a controller, power switches and the necessary passive components—all of which are fully tested and pre-characterized for EMI and DC performance—to offer a complete switching power supply solution. Offered in an ultra-compact, rugged and thermally enhanced package to improve high power density in your designs, these modules simplify your power design process while offering exceptional performance. Utilizing our proprietary Hyper Speed Control® architecture, they are designed to offer fast load transients to minimize output capacitance. Their HyperLight Load® mode provides efficiency improvements for light-load operation.
Microchip offers a comprehensive portfolio of power switches to help provide solutions for power distribution and power savings, circuit protection including short circuit and overcurrent fault events, and charge emulation for USB port power.
Voltage Supervisor and Voltage Reference products monitor system voltages to eliminate problems during operation. On power-down, the supervisor monitors the power supply voltage and resets the system if the voltage falls below a predetermined level. On power-up, the supervisor holds the system in reset until the voltage has stabilized.
System and CPU Supervisors and Voltage Detector products monitor system voltages to eliminate problems during operation. On power-down, the supervisor monitors the power supply voltage and resets the system if the voltage falls below a predetermined level. On power-up, the supervisor holds the system in reset until the voltage has stabilized.
Microchip offers several families of series and shunt voltage references, with options for high-accuracy, low-noise and general purpose use. These devices provide a stable reference for a wide variety of data conversion and signal conditioning applications.
