Product Summary

The LNK304DN is a Lowest Component Count, Energy-Efficient Off-Line Switcher IC. The LNK304DN is designed to replace all linear and capacitor-fed (cap dropper) non-isolated power supplies in the under 360mA output current range at equal system cost while offering much higher performance and energy efficiency. The applications of the LNK304DN include Appliances and timers, LED drivers and industrial controls.


Parametrics

LNK304DN absolute maximum ratings: (1)DRAIN Voltage: -0.3V to 700V; (2)Peak DRAIN Current: 400mA; (3)FEEDBACK Voltage: -0.3V to 9V; (4)FEEDBACK Current: 100mA; (5)BYPASS Voltage: -0.3V to 9V; (6)Storage Temperature: -65℃ to 150℃; (7)Operating Junction Temperature: -40℃ to 150℃; (8)Lead Temperature: 260℃.

Features

LNK304DN features: (1)Lowest cost and component count buck converter solution; (2)Fully integrated auto-restart for short-circuit and open loop fault protection-saves external component costs; (3)LNK302 uses a simplified controller without auto-restart for very low system cost; (4)66 kHz operation with accurate current limit-allows low cost off-the-shelf 1mH inductor for up to 120mA output current; (5)Tight tolerances and negligible temperature variation; (6)High breakdown voltage of 700V provides excellent input surge withstand; (7)Frequency jittering dramatically reduces EMI (~10dB) minimizes EMI filter cost; (8)High thermal shutdown temperature (+135℃ minimum).
