QX2303
The QX2303 is a highly efficient, low-power, low-ripple, high-frequency PFM synchronous boost DC-DC converter.
The QX2303 requires only three external components to boost a low input battery voltage to the required operating voltage.
The output voltage of the QX2303 can be selected via internal adjustment (0.1V steps), making it convenient for customers to use in different output load situations.
The QX2303 system output voltage features low ripple and low noise.
The built-in synchronous switch in the QX2303 greatly reduces losses on the switch, enabling efficiency up to 95%.
The QX2303 operates in PFM mode, effectively reducing losses in light load mode and improving device lifespan. At the same time, the chip's low quiescent current further reduces system losses.
