IRIS-F6456S

Features

鈥?/div>

Oscillator is provided on the monolithic control with adopting On-Chip-

Trimming technology.

鈥?/div>

Small temperature characteristics variation by adopting a comparator to

compensate for temperature on the control part.

鈥?/div>

Low start-up circuit current (100uA max)

鈥?/div>

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

load

鈥?/div>

Avalanche energy guaranteed MOSFET with high VDSS

鈥?/div>

The built-in power MOSFET simplifies the surge absorption circuit

since the MOSFET guarantees the avalanche energy.

鈥?/div>

No VDSS de-rating is required.

鈥?/div>

Built-in constant voltage drive circuit

鈥?/div>

Built-in soft drive circuit

鈥?/div>

Built-in low frequency PRC mode (鈮?0kHz)

鈥?/div>

Various kinds of protection functions

鈥?/div>

Pulse-by-pulse Overcurrent Protection (OCP)

鈥?/div>

Overvoltage Protection with latch mode (OVP)

鈥?/div>

Thermal Shutdown with latch mode (TSD)

Descriptions

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.

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 鈥淧ulse Ratio Control鈥?(On-width control with fixed

OFF-time).
