TLE6389 General 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.

These step-down controllers drive an external P-channel MOSFET, allowing design flexibility for applications up to 3A. A high switching frequency (up to 350kHz) and operation in continuous- onduction 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 (TLE6389-50) or 3.3V (TLE6389-33) and adjustable for the TLE6389. Input voltages can be up to 60V.
