产品概述 返回TOP
CXSU63252 is a high efficiency, synchronous, step-up Boost converter designed for one-cell Li-Ion or Li-polymer, or a two to three-cell alkaline Ni-Cd or Ni-MH battery powered applications. It can convert down to 2.5V input voltage and up to 5.5V output voltage. It adopts NMOS for the main switch and PMOS for the synchronous switch.CXSU63252 can disconnect the output from input during the shutdown mode. When input voltage exceeds the regulated output voltage, CXSU63252 enters bypass mode automatically.
