Introduction

AI Translation

The Micrel MIC23050 is a high-efficiency, 600mA, PWM, synchronous buck (step-down) regulator featuring the HyperLight Load™ patented 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 also 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 to 2.2μH and uses a small output capacitor that enables a sub-1mm height. In contrast to traditional light load schemes, the 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. The MIC23050 is available in an 8-pin 2mm×2mm MLF with a junction operating range from -40°C to +125°C.
