Power Management iCs
iC-Haus' Power Management iCs provide flexible autarky power supply solutions for industrial and automotive applications from a wide supply voltage range.
These iCs offer a wide functionality in a small footprint, being ideal for compact solutions. The switched-mode supply and linear regulator integrated in the same silicon provide stable supply voltages with high efficiency in comparison to traditional solutions. Dual independent outputs are ideal for separated digital and analog voltage supplies, reducing interference and allowing different supply voltages from one single iC.
Applications:
- Industrial sensors
- Rotary and linear encoders
