IRIS-G6351S Datasheet, PDF (1/7 Pages) International Rectifier – INTEGRATED SWITCHER

Data Sheet No. PD 96945A
IRIS-G6351S
Features
• Oscillator is provided on the monolithic control with adopting On-Chip-
Trimming technology.
INTEGRATED SWITCHER
Package Outline
• Small temperature characteristics variation by adopting a comparator to
compensate for temperature on the control part.
• Low start-up circuit current (50uA 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
• Various kinds of protection functions
• Pulse-by-pulse Overcurrent Protection (OCP)
• Overvoltage Protection with latch mode (OVP)
• Thermal Shutdown with latch mode (TSD)

Descriptions
Note 1: The Pout (W) represents the thermal rating at PRC 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-G6351S is a hybrid IC consists from power MOSFET and a controller IC, designed for PRC fly-back converter
type SMPS (Switching Mode Power Supply) applications. This IC realizes 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).
