The 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 draw of 20µA and can achieve over 83% efficiency even at 1mA.
In contrast to traditional light load schemes, the HyperLight Load® architecture does need 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 output voltage options from 0.72V to 3.3V thereby eliminating external feedback components.
The MIC33050 is available in an 12-pin 3mm x 3mm with a operating junction range of -40°C to +125°C.
