The IFX80471 step-down DC-DC switching controllers provide high efficiency over loads ranging from 1mA up to 2.3A. A unique PWM/PFM control scheme operates with a duty cycle up to 100% resulting in a very low dropout voltage. This control scheme eliminates minimum load requirements and reduces the supply current under light loads to 120μA, depending on dimensioning of external components.
