  • Applications

The QX2303 Series are PFM step-up DC-DC converters with high efficiency, low ripple and high operation frequency. The QX2303 Series need only four external components to realize step-up conversion from low input battery voltage to the voltage needed, and they are applied to one to four battery- cells application.

The QX2303 Series adopt low dissipation and high performance reference circuit, with trimming technique in manufacture, which ensure high precision and low temperature drift of the output voltage. The precision of output voltage precede ±2.5%, and the highest efficiency is 89%.

The QX2303 Series have four package types: SOT23, SOT23-5, SOT89-3 and TO-92. For SOT23-5 package, an enable pin “EN” is provided so that the operation state of the converter can be controlled. When EN is low, the converter is in power saving mode, which decreases power dissipation to the minimum.
