ACT6906 Description
The ACT6906 is a fixed-frequency current-mode synchronous PWM step down converter that is capable of delivering 600mA of output current while achieving peak efficiency of 95%. Under light load conditions, the ACT6906 operates in a proprietary pulse skipping mode that consumes just 24µA of supply current, maximizing battery life in portable applications. The ACT6906 operates with a fixed frequency of 1.6MHz, minimizing noise in noise-sensitive applications and allowing the use of small external components. The ACT6906 is an ideal solution for applications powered by Li-Ion batteries or other portable applications that require small board space.
