QX2304 is a PFM synchronous boost DC-DC converter with high efficiency, low power consumption, low ripple and high operating frequency.

The QX2304 requires only three peripheral components to convert and boost the low input battery voltage to the required operating voltage.

The output voltage of QX2304 can be selected by internal adjustment (step 0.1V), which is convenient for customers to apply to different output load conditions.

The output voltage of QX2304 system has the characteristics of low ripple and low noise.

The built-in synchronous switching tube of QX2304 can greatly reduce the loss on the switching tube, and the efficiency can reach up to 95%.

QX2304 works in PFM mode, which can effectively reduce the loss in light load mode and improve the service life of the device. At the same time, the low quiescent current of the chip can further reduce system losses.
