Description
The MIC33050 is a high-efficiency 600 mA PWM synchronous buck (step-down) regulator with internal inductor featuring HyperLight Load®, a 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 20 µA and can achieve over 85% efficiency even at 1 mA. 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.
At higher loads, the MIC33050 provides a nearly constant switching frequency of greater than 4 MHz while providing peak efficiencies greater than 93%.
The MIC33050 is available in fixed and adjustable output voltages and comes in a 12-pin 3 mm x 3 mm HDFN with a junction operating range of –40°C to +125°C.
