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 100µA.
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
