The ACT6308 is a high efficiency synchronous step-up DC/DC converter that consumes just 17μA of quiescent supply 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 89% and features a proprietary control scheme that ensures high efficiency over a wide load current range.
The ACT6308 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 ACT6308 is available in a tiny SOT23-5 package.
