MIC23050
4MHz PWM Buck Regulator with
HyperLight Load? Switching Scheme
General Description
Features
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

The MIC23050 is available in an 8-pin 2mm x 2mm MLF
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.
