TLE6389 Product details

Description

adjustable 5V, Device Enable 5V, SI GND, SI Enable 3.3V, Device Enable 3.3V, SI GND, SI Enable 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 extern
