SY8009 datasheet


Description :

The SY8009A and SY8009B are high-efficiency, high frequency synchronous  step-down  DC-DC  regulator ICs  capable  of  delivering  up  to  1.5A/2A  output currents.

The SY8009 family operate over a wide input voltage  range  from  3V  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 greater than 1MHz switching frequency.
