 Step-Down DC/DC Controller

 The TLE6389 step-down DC-DC switching controllers provide high efficiency over loads ranging from 1mA up to 2.5A. A unique PWM/PFM control scheme operates with up to a 100% duty cycle, resulting in 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. In addition the adjustable version TLE6389-2GV can be shut down via the Enable input reducing the input current to 2µA.
