QX2329L50F
QX2329L50F, SOT23-5, boost IC .
The QX2329 is a synchronous boost converter with only 6UA quiescent current.
QX2329 adopts independent patented technology on the basis of PFM. On the one hand, it eliminates the influence of the converter output capacitor ESR on stability and improves the steady-state accuracy of the output voltage; At the same time, it can maintain ultra-low quiescent current and achieve high efficiency.
The output voltage of the QX2329 can be internally adjusted to achieve fixed output voltage regulation from 1.8V to 5.0V in steps of 0.1V.
The QX2329 requires only three peripheral components to achieve the desired output voltage and supports small external inductors and output capacitors.
The QX2329 also supports high output current applications with Schottky diodes.
The QX2329 is available in SOT 23, SOT 23-5 and SOT 89-3 packages.
