A6159 Datasheet | International Rectifier

Data Sheet No. PD 96934A IRIS-A6159 - Small sized 8-pin DIP type full molded package, optimum IC for lowheight SMPS - Off-timer circuit is provided on the monolithic control IC Package Outline - Low start-up circuit current (10u A typ) - Low circuit current at operation (1.5m A 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 8 Lead PDIP - Built-in Leading Edge Blanking Function - Built-in constant voltage drive circuit Key Specifications - Various kinds of protection functions MOSFET RDS(ON) Pulse-by-pulse Overcurrent Protection (OCP) Type VDSS(V) MAX ACinput(V) Overload Protection with auto recovery (OLP) 230±15% Overvoltage Protection with latch mode (OVP) Thermal Shutdown with latch mode (TSD) 85 to 264 IRIS-A6159 650 6Ω Features INTEGRATED SWITCHER Pout(W) Note 1 7 5 Descriptions IRIS-A6159 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 ponent count and simplifying the circuit design. Note: PRC is abbreviation for “Pulse Ratio Control” (On-width control with fixed OFF-time).
