XR6503D

XR6503/XR6503D _____________________________ _______ __ SYNCHRONOUS BOOST CONVERTER With 6A Switch, Can Output 5V 2.5A with Li-Battery Input GENERAL DESCRIPTION XR6503/XR6503D is a high efficiency synchronous boost regulator that converts down to 2.5V input and 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. FEATURES  2.5V Minimum input voltage  Adjustable output voltage  6A peak current limit  Input under voltage lockout  600Khz fixed Switching Frequency  Load disconnect during shutdown  Integrated soft-start  Output over voltage protection  30mohm Power MOSFET  Thermal Shutdown  SOP8-PP Package APPLICATIONS Handheld Devices Power Bank All Single Cell Li or Dual Cell Battery Operated Products XySemi Inc Figure 1.
