Description

IRIS-G5653 is a hybrid IC consists from power MOSFET and a controller IC, designed for Indirect feed-back Quasi-Resonant (including low frequency PRC) fly-back converter type SMPS (Switching Mode Power Supply) applications.

Features

• 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)

• Built-in Active Low-Pass Filter for stabilizing the operation in case of light load

• 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.

• Indirect feed-back by built-in error amplifier on Vin terminal
