The CXSD62331 is a high efficiency monolithic synchronous step-down regulator using 1.4MHz constant frequency, current mode architecture. The device is available in an adjustable version. It is ideal for portable equipment requiring very high current up to 2A from single-cell Li-ion batteries while still achieving over 95% efficiency during peak load conditions. The CXSD62331 can enter PFM (low I_Q) mode with typically 55μA quiescent current for highest light load efficiency to maximize battery life.RnL嘉泰姆

The CXSD62331 also can run at 100% duty cycle for low dropout operation, extending battery life in portable systems while light load operation provides very low output ripple for noise sensitive applications. It can supply up to 2A output load current from a 2.5V to 5.5V input voltage and the output voltage can be regulated as low as 1.2V. The high switching frequency (1.4MHz) minimizes the size of external components while keeping switching losses low. The internal slope compensation setting allows the device to operate with smaller inductor values to optimize size and provide efficient operation.RnL嘉泰姆

CXSD62331 is available in both adjustable and fixed (1.2V, 1.8V, 3.3V) output voltage versions; in the Green TDFN-3×3-10L package. It is rated over the -40℃ to +85℃ temperature range.RnL嘉泰姆
