Features & Applications
The MIC33050-4YHL TR is a high efficiency 600 mA 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 20 µA and can achieve over 83% efficiency even at 1 mA. At higher loads, the MIC33050 provides a constant switching frequency of greater than 4 MHz while providing peak efficiencies greater than 93%. The MIC33050 is available in fixed output voltage options from 0.72 V to 3.3 V thereby eliminating external feedback components.
