A6159 Datasheet IRIS-A6159

Manufacturer: International Rectifier (now Infineon)

General Description

s 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 component count and simplifying the circuit design.

Note: PRC is abbreviation for “Pulse Ratio Control” (On-width control with fixed OFF-time).

Overview

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 (10uA typ) •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.
