General Descriptions
The  STR-A6100  series  are  power  ICs  for  switching power supplies, incorporating a MOSFET and a current
mode PRC controller IC. PRC  (Pulse  Ratio  Control)  controls  on-time  with fixed off-time.
The  IC  includes  a  startup  circuit  and  a  standby function to achieve the low standby power. The rich set
of  protection  features  helps  to  realize  low  component counts, and high performance-to-cost power supply.
