Device Overview

Summary

The MIC23050 is a high efficiency 600mA PWM synchronous buck (step-down) regulator featuring HyperLight Load®, a patent pending switching scheme that offers best in class light load efficiency and transient performance while providing very small external components and low output ripple at all loads.

The MIC23050 has a very low typical quiescent current draw of 20µA and can achieve over 89% efficiency even at 1mA. The device allows operation with a tiny inductor ranging from 0.47µH or 2.2µH while using small output capacitors, enabling a sub 1mm height solution.

In contrast to traditional light load schemes HyperLight Load® architecture does not need to trade off control speed to obtain low standby currents and in doing so the device only needs a small output capacitor to absorb the load transient as the powered device goes from light load to full load.

At higher loads the MIC23050 provides a constant switching frequency of greater than 4MHz while providing peak efficiencies greater than 93%.

The MIC23050 comes in fixed output voltage options from 0.72V to 3.3V eliminating external feedback components.
