General Description
The  G5108  boost  converter  in  corporate  high-per-formance,  current-mode,  frequency  selectable  pulse  width  modulation  (PWM)  circuitry  with  a  built-in  0.2Ωn-channel  MOSFET  to  provide  a  highly  efficient  regu-lator.

High  switching  frequency  allows  easy  filtering  and  faster  loop  performance.  An  external  compensation  pin provides the user flexibility in determining loop dy-namics,  allowing  the  use  of  small,  low  ESR  ceramic  output  capacitors.  The  device  can  produce  an  output  voltage  as  high  as  20V.  User  programmed  soft-start  with an external capacitor determines the input current ramp rate.   

The  G5108  is  available  in  a  space-saving  MSOP-8  and TDFN3X3-8 package.
