一,产品概述(General Description)         
        JTM5177 is a high efficiency synchronous boost regulator that converts down to 2.5V
input and up to 5.5V output voltage. It adopts NMOS for the main switch and
PMOS for the synchronous switch. It can disconnect the output from input during the
shutdown mode.. It integrates 6A power MOSFET and can output 5V 2.5A with Li-Battery input.
