| ACT6906 1.6MHz, 600mA Synchronous Step Down Converter in SOT23-5 High Efficiency - Up to 95% Very Low 24µA Quiescent Current Guaranteed 600mA Output Current 1.6MHz Constant Frequency Operation Internal Synchronous Rectifier Eliminates Schottky Diode Adjustable Output Voltages From 0.6V to VIN Fixed Output Voltage Options Available 100% Duty Cycle Low-Dropout Operation 0.1µA Shutdown Current Tiny SOT23-5 Package Blue Tooth Headsets Portable Audio Players Mobile Phones Wireless and DSL Modems Digital Still Cameras Portable Instruments The ACT6906 is a fixed-frequency currentmode synchronous PWM step down converter that is capable of delivering 600mA of output current while achieving peak efficiency of 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. The ACT6906 is available in a variety of fixed output voltage options, 1.5V, 1.8V, and 2.5V, and is also available in an adjustable output voltage version capable of generating output voltages from 0.6V to VIN .The ACT6906 is available in a tiny 5-pin SOT23-5 package.
