The TLE6389-3G V50 Electronic Components 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

The TLE6389-3G V50  step-down DC-DC controllers are designed primarily for use in Automotive applications where high input voltage range requirements have to be met. Using an external P-MOSFET and current-sense resistor allows design flexibility and the improved efficiencies associated with high-performance P-channel MOSFETs. 

The unique, peak current-limited, PWM/PFM control scheme gives these devices excellent efficiency over wide load ranges, while drawing around 100µA current from the battery under no load condition.
