... TLE 6389 G33-1 on request Functional description The TLE6389 step-down DC-DC switching controllers provide high efficiency over loads ranging from 1mA up to 3A. A unique PWM/PFM control scheme operates with 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 100µA. ...

... Detailed Description The TLE6389 family is a family of step-down DC-DC controllers designed primarily for use in high voltage applications such as automotive. Using an external MOSFET and current-sense resistor allows design flexibility and the improved efficiencies associated with high-performance P-channel MOSFETs. A unique, current-limited, pulse-width (PWM)/pulse-frequency-modulated (PFM) control scheme gives these devices excellent efficiency over load ranges up to three decades, while drawing less than 100µ ...

... Duty-Cycle Operation and Dropout The TLE6389 operates with a duty cycle up to 100%. This feature extends allows to operate with the lowest possible drop at low battery voltage as it occurs at cold ambient temperatures. The MOSFET is turned on continuously when the supply voltage approaches the output voltage ...

... SYNC Input and Frequency Control The TLE6389’s internal oscillator is set for a fixed-switching frequency of 360kHz or can be synchronized to an external clock. Do not leave SYNC unconnected. Connecting SYNC to GND enables PWM/PFM operation to reduce supply current at light loads. SYNC is a negative-edge triggered input that allows synchronization to an external frequency ranging between 270kHz and 450kHz ...
