Low Input High Efficiency Synchronous Step-Up DC/DC Converter

www.DataSheet4U.com ACT6305 Low Input High Efficiency Synchronous Step-Up DC/DC Converter FEATURES • • • • • • 1V Typical Startup Voltage Up to 94% Efficiency Fully Integrated Power Stage Fixed 3.3V/5V or Adjustable Output Voltage NanoStandbyTM Shutdown Mode Tiny SOT23-5 Package − RoHS Compliant Package Rev0, 13-May-08 GENERAL DESCRIPTION The ACT6305 is a high efficiency synchronous step-up DC/DC converter that consumes just 17µA of quiescent supply current and is capable of delivering more than 400mA output current using only three external components. This device achieves a typical startup voltage of just 1V, making it ideal for applications operating from 1 or 2 alkaline cells. This device incorporates an internal synchronous rectifier, and achieves excellent peak efficiency of up to 94% and features a proprietary control scheme that ensures high efficiency over a wide load current range. The ACT6305 features pin-selectable output voltages of 3.3V or 5V, or it can also be set externally to any voltage between 2V and 5V. The ACT6305 is available in a tiny SOT23-5 package.
