INTRODUCTION
STR-A6300 series is a hybrid IC with a built-in power MOSFET and a controller IC, designed for fly-back converter type SMPS(Switching Mode Power Supply) applications, packaged into DIP8, applicable for PRC operation only for small power SMPS.
This IC realizes downsizing and standardizing of a power supply system that reduces external components count and simplifies circuit designs.
(Note) PRC is abbreviation of “Pulse Ratio Control”(On-width control with fixed OFF-time).

FEATURES
● Small sized 8-pin DIP type full molded package, optimum IC for low-height SMPS
● Oscillator is incorporated in the monolithic control IC
   with adopting On-Chip-Trimming technology.
● Small temperature characteristics variation by adopting a comparator
   compensated for temperature in the control part
● Low start-up circuit current(50uA max)
● Built-in Active Low-Pass Filter for stabilizing the operation at light load
● Avalanche energy guaranteed MOSFET with high VDSS
   • The built-in power MOSFET simplifies the surge absorption circuit since
      the MOSFET guarantees the avalanche energy.
   • No VDSS de-rating is required.
● Built-in constant voltage drive circuit
● Various kinds of protection functions
   • Pulse-by-pulse Overcurrent Protection(OCP)
   • Overvoltage Protection with latch mode (OVP)
   • Thermal Shutdown with latch mode (TSD)
