GENERAL DESCRIPTION
The ACT6305 high efficiency synchronous
step-up DC/DC converter is capable of delivering
more than 400mA output current using only three
external components.
Typical startup voltage is 0.9V and the device
can operate down to a 0.6V input voltage. Using
an internal synchronous rectifier, the ACT6305
can achieve high efficiency of up to 94%.
Variable switching frequency operation results in
high efficiency for a wide range of load.
The output voltage is selectable between
3.3V and 5V, or can be externally set to any
voltage between 2V and 5V. The IC is available
in space-saving SOT23-5 package and in SOP-8
package.
