MIC33050
4MHz Internal Inductor PWM Buck
Regulator with HyperLight Load ?
General Description
The Micrel MIC33050 is a high-efficiency 600mA PWM
synchronous buck (step-down) regulator with internal
inductor 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 MIC33050 also has a very-low typical quiescent
current of 20μA and can achieve over 85% efficiency even
at 1mA.
In contrast to traditional light load schemes, the HyperLight
Load architecture does not 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 MIC33050 provides a constant
switching frequency of greater than 4MHz while providing
peak efficiencies greater than 93% .
The MIC33050 is available in fixed and adjustable output
voltages and comes in a 12-pin 3mm x 3mm MLF ? with a
junction operating range of –40 ? C to +125 ? C.
