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.
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 ...
