SY8008 General Description
The  SY8008A,  SY8008B  and  SY8008C  are  high-efficiency  1.5MHz  synchronous  step-down  DC-DC regulator  ICs  capable  of  delivering  up  to  1.2A  output currents. The SY8008 family operate over a wide input voltage  range  from  2.5V  to  5.5V  and  integrate  main switch and synchronous  switch with very  low RDS(ON) to minimize the conduction loss.  Low output voltage  ripple and  small external  inductor and  capacitor  sizes  are  achieved  with  1.5MHz switching  frequency.  This  along  with  small  SOT-23/TSOT-23  footprint  provides  small  PCB  area application.

SY8008 Applications  
· Portable Navigation Device
· Smart phone
· USB Dongle
· Set Top Box
· Media Player
