IRIS-F6456S

INTEGRATED SWITCHER

Package Outline

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.

• Built-in constant voltage drive circuit

• Built-in soft drive circuit

TO-247 Fullpack (5 Lead)

Key Specifications

• Built-in low frequency PRC mode (≒20kHz)

• Various kinds of protection functions

Note 1: The Pout (W) represents the thermal rating at Quasi-Resonant

Operation, and the peak power output is obtained by approximately 120

to 140% of the above listed. When the output voltage is low and ON-

duty is narrow, the Pout (W) shall become lower than that of above.

Descriptions

IRIS-F6456S is a hybrid IC consists from power MOSFET and a controller IC, designed for Quasi-Resonant (including

low frequency PRC) 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 components count

and simplifying the circuit designs. (Note). PRC is abbreviation of “Pulse Ratio Control” (On-width control with fixed

OFF-time).
