   产品概述 返回TOP0We嘉泰姆

The CXSD62328 is a high efficiency monolithic synchronous step-down regulator using 1.5MHz constant frequency, current mode architecture. The device is available in an adjustable version and fixed output voltages of 1.2V, 1.8V and 3.3V. It is ideal for portable equipment requiring very high current up to 2A from single-cell Lithium-ion batteries.

The CXSD62328 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 0.6V. The high switching frequency (1.5MHz) 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.0We嘉泰姆

The CXSD62328 is available in Green TDFN-3×3-10L package and is rated over the -40℃ to +85℃ temperature range.0We嘉泰姆
