MIC23050

4MHz PWM Buck Regulator with

HyperLight Load™ Switching Scheme

General Description

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 x 2mm MLF

with a junction operating range from –40°C to +125°C.
