PD 96949A IRIS-G6651 Features • Oscillator is provided on the monolithic control with adopting On-ChipTrimming 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 • 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) IRIS-G6651 650 3.
9Ω INTEGRATED SWITCHER Package Outline TO-220 Fullpack (5 Lead) Key Specifications Type MOSFET VDSS(V) RDS(ON) MAX AC input(V) 230±15% 85 to 264 Pout(W) Note 1 66 30 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-G6651 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).
