General Description

IRIS-X6757 is a hybrid IC consisting of a power MOSFET and a controller IC, designed for Quasi-Resonant (including low frequency PWM) fly-back converter type SMPS (Switching Mode Power Supply) applications.

This IC realizes high efficiency, low noise, downsizing and standardizing of a power supply system reducing external component count and simplifying the circuit design.

Typical Connection Diagram      Note 1: The Pout (W) represents the thermal rating at Quasi-Resonant operation, and the peak power output is obtained by approximating 120 to 140 % of the above listed value.

Key Features

  • 7-pin SIP type full molded package, optimum IC for low-height SMPS.
  • Oscillator is provided on the monolithic control with adopting On-Chip Trimming Technology.
  • Small temperature characteristics variation by adopting a comparator to compensate for temperature on the control part.
  • Low start-up circuit current (100uA max).
  • Avalanche energy guaranteed MOSFET with high VDSS The built-in power MOSFET simplifies the surge absorption circuit since the MOSFE.
