IRISA6131

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 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 8 Lead PDIP Built-in constant voltage drive circuit Various kinds of protection functions Pulse-by-pulse Overcurrent Protection (OCP) Key Specifications Overvoltage Protection with latch mode (OVP) MOSFET RDS(ON) Thermal Shutdown with latch mode (TSD) Features INTEGRATED SWITCHER Type VDSS(V) 500 MAX ACinput(V) Pout(W) Note 1 10 Descriptions IRIS-A6131 3.95Ω 100/120±15% 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 opera...
