Note: The following information is given as a hint for the implementation of the device
7.1
The TLE 6389 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. This wide dynamic range optimizes the TLE 6389 for
automotive applications, where load currents can vary considerably as individual circuit
blocks are turned on and off to conserve energy. Operation to a 100% duty cycle allows
the lowest possible dropout voltage, maintaining operation during cold cranking. High
switching frequencies and a simple circuit topology minimize PC board area and
component costs.
