Description

The ACT6907 is a fixed-frequency currentmode 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 ACT6907 operates in a proprietary pulse skipping mode that consumes just 24A of supply current, maximizing battery life in portable applications. The ACT6907 operates with a fixed frequency of 1.6MHz, minimizing noise in noise-sensitive applications and allowing the use of small external components. The ACT6907 is an ideal solution for applications powered by Li-Ion batteries or other portable applications that require small board space.

The ACT6907 is available in a variety of fixed output voltage options, 1.5V, 1.8V, 2.5V, 2.7V, 2.8V, and 3.3V, and is also available in an adjustable output voltage version capable of generating output voltages from 0.6V to VIN .The ACT6907 is available in the tiny 5-pin SOT23-5 package.
