IRIS-A6131 •Small sized 8-pin DIP type full molded package, optimum IC for lowheight 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 power0.
1W at no load) •Auto Bias Function (stable burst op...
