High Efficiency 10A Synchronous Buck Converter

General Description

G5335  is  a  10A,  synchronous  DC/DC  buck  converter  with  integrated  20mΩ  N-channel  high-side  MOSFETand 8.5mΩ N-channel low-side MOSFET. It uses con-stant   on-time   control   scheme   to   handle   wide   in-put/output voltage ratios with ease and provides 100ns “instant-on”  response  to  load  transients  while  main-taining  a  relatively  constant  switching  frequency.  The  G5335  achieves  high  efficiency  at  a  reduced  cost  by  eliminating  the  current-sense  resistor  found  in  tradi-tional current-mode PWMs. Single-stage buck conver-sion   allows   these   devices   to   directly   step   down   high-voltage  batteries  for  the  highest  possible  effi-ciency. The G5335 is intended for the power supply of Notebook  Computer,  or  other  low-voltage  supplies  as  low  as  0.8V.  The  G5335  is  available  in  QFN4X4-23  package.
