IRIS-G5624A

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 step drive circuit

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

• Various kinds of protection functions

• Pulse-by-pulse Overcurrent Protection (OCP)

• Overvoltage Protection with latch mode (OVP)

• Thermal Shutdown with latch mode (TSD)

Descriptions

IRIS-G5624A is a hybrid IC consists from power MOSFET and a controller IC, designed for Indirect feed-back Quasi-

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).
