IRIS-A6131  
INTEGRATED SWITCHER  
Features  
Small sized 8-pin DIP type full molded package, optimum IC for low-  
height SMPS  
Off-timer circuit is provided on the monolithic control IC  
Low start-up circuit current (10uA max)  
Package Outline  
Low circuit current at operation (1.5mA typ)  
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 Start-up circuit (the power loss in the start-up circuit is  
reduced by cutting off the start-up circuit after the IC starts its  
operation.)  
Auto Burst Stand-by (realizing input power<0.1W at no load)  
Auto Bias Function (stable burst operation without the interference on  
transformer)  
Two operational modes by auto switching functions  
For normal operation: PRC mode  
For stand-by operation (at light load): Burst mode  
Built-in Leading Edge Blanking Function  
Built-in constant voltage drive circuit  
8 Lead PDIP  
Various kinds of protection functions  
Pulse-by-pulse Overcurrent Protection (OCP)  
Overvoltage Protection with latch mode (OVP)  
Thermal Shutdown with latch mode (TSD)

Descriptions  
IRIS-A6131 is a hybrid IC consisting of a power MOSFET and a controller IC, designed for PRC  
fly-back converter type SMPS (Switching Mode Power Supply) applications, applicable for PRC  
operation for small power SMPS. This IC realizes downsizing and standardizing of a power supply  
system reducing external component count and simplifying the circuit design.  
Note: PRC is abbreviation for “Pulse Ratio Control” (On-width control with fixed OFF-time).

Note 1: The pout (W) represents the thermal rating at PRC Operation. The peak power output is obtained by  
approximating 120 to 140% of the above listed value. When the output voltage is low and ON-duty is narrow, the  
Pout (W) shall become lower than that of above value.
