QX2304
Synchronous PFM Step-up DC-DC Converter
General Description
The QX2304 Series are synchronous PFM step-up DC-DC converters with very low ripple noise due to the high operating frequency, and the maximum operating frequency is 300KHz .
The output voltagesof The QX2304 Series can be programmable from 2.5V to 3.6V in0.1Vsteps.
QX2304 has high efficiency up to 95%.
An enable pin (EN) is provided so that the circuit can be powered down.
only three components are required to realize the voltage step-up conversion.
