Short 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 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 100A.
For the start up procedure a slow start feature is implemented to avoid overshoots at the
output. The TLE6389 step-down controllers drive an external P-channel MOSFET,
allowing design flexibility for applications up to 15W of output power. A high switching
frequency and operation in continuous-conduction mode allow the use of tiny surface-
mount inductors. Output capacitor requirements are also reduced, minimizing PC board
area and system costs. The output voltage is preset at 5V (TLE6389G50-1 and
TLE6389G50) and adjustable for the TLE6389GV. Input voltages can be up to 60V.
