MIC23050
4MHz PWM Buck Regulator with HyperLight Load™ Switching Scheme
General Description
Features
The Micrel MIC23050 is a high-efficiency, 600mA, PWM, synchronous buck (step-down) regulator featuring the HyperLight Load™ patented 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
HyperLight Load™
• 600mA output current
• Fixed output voltage from 0.72V to 3.3V
• Ultra-fast transient response
• 20µA typical quiescent current
The MIC23050 also has a very-low typical quiescent current draw of 20µA and can achieve over 89% efficiency even at 1mA. The device allows operation with a tiny inductor ranging from 0.47µH to 2.
