IRIS-X6757

IRIS-X6757 Features 7-pin SIP type full molded package, optimum IC for low-height SMPS. 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) 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 PWM mode ( 22 kHz) UVLO Burst Standby Two operational modes by auto switching functions according to load TO-220 Fullpack (7 Lead) For middle~heavy load operation : QR mode For light~middle load operation : 1 Bottom Skip mode Key Specifications Various kinds of protection functions Pulse-by-Pulse Overcurrent Protection (OCP) MOSFET RDS(ON) Overvoltage Protection with Latch mode (OVP) T ype VDSS(V) MAX AC input(V) Overload Protection with Latch mode (OLP) 230 15% The maximum limit of on-time IRIS-X6757 650 85 to 264 INTEGRATED SWITCHER Package Outline Pout(W) Note 1 300 180 Description IRIS-X6757 is a hybrid IC consisting of a power MOSFET and a controller IC, designed for Quasi-Resonant (including low frequency PWM) fly-back converter type SMPS (Switching Mode Power Supply) applications. This IC realizes high efficiency, low noise, down...
