STR-A6300 Application Notes

（Ver.1.2）

1 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).

2 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)
