MIC33050  
4MHz Internal Inductor PWM Buck  
Regulator with HyperLight Load®  
General Description  
Features  
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.  
Input voltage: 2.7V to 5.5V  
600mA output current  
Fixed and adjustable output voltage options  
No external inductor required  
Ultra-fast transient response  
20µA quiescent current  
4MHz switching in PWM mode  
Low output voltage ripple  
>93% peak efficiency  
The MIC33050 also has a very-low typical quiescent  
current of 20µA and can achieve over 85% efficiency even  
at 1mA.  
>85% efficiency 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.  
Micropower shutdown  
12-pin 3mm x 3mm MLF®  
–40C to +125C junction temperature range  
Applications  
At higher loads, the MIC33050 provides a constant  
switching frequency of greater than 4MHz while providing  
peak efficiencies greater than 93%.  
Cellular phones  
Digital cameras  
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 –40C to +125C.
