The TLE6389-2GV step-down DC-DC switching controllers provide high efficiency over loads ranging from 1mA up to 2.5A. The TLE6389 features a unique PWM/PFM control scheme enabling a 100% duty cycle, resulting in low dropout voltage and eliminating minimum load requirements. Its adjustable version, TLE6389-2GV, can be shut down via the Enable input, reducing input current to <2μA. The step-down controllers offer design flexibility for up to 12.5W output power and can accommodate input voltages of up to 60V.
