Features & Applications
The MIC23250-SKYMT TR is a high efficiency 4 MHz dual 400 mA synchronous buck regulator with HyperLight Load™. HyperLight Load™ provides all the advantages of standard light load modes, such as low quiescent current and high efficiency but also allows the use of very small output capacitors to maintain low output ripple voltage throughout the entire load range.

 

This benefit is not possible with other light load mode types as they trade off control speed for low standby currents. With HyperLight Load™, the output capacitor can be reduced by up to a factor of 20 saving cost and valuable board space. The device is designed for use with a 1 µH inductor and a 4.7 µF output capacitor that enables a sub-1 mm height solution.
