The CXSD62330 is a 1.6MHz, constant frequency, current mode, synchronous, step-down switching regulator. It can deliver 600mA load current from 2.5V to 5.5V input voltage, and output voltage can be as low as 0.6V.
High switching frequency minimizes the sizes of inductor and capacitor. Integrated power MOSFETs and internal compensation make the CXSD62330 simple to use and fit the total solution in a compact space.
The CXSD62330 can also run at 100% duty cycle for low dropout operation, extending battery life in portable system. The synchronous architecture eliminates the external Schottky diode, and achieves over 90% of the power conversion efficiency. Low output ripple voltage at light load, 30μA quiescent current and less than 1μA of shutdown current make CXSD62330 the ideal power supply solution for portable applications.
CXSD62330 is available in both adjustable and fixed (1.2V, 1.8V, 3.3V) output voltage versions. It is in the Green TSOT-23-5 and TDFN-2×2-6L packages. It is rated over the -40℃ to +85℃ temperature range.
