Product Summary
The LNK304GN is a lowest component count, energy efficient off-line switcher IC. It is specifically designed to replace all linear and capacitor-fed (cap dropper) non-isolated power supplies in the under 360 mA output current range at equal system cost while offering much higher performance and energy efficiency. The applications of the LNK304GN include: Appliances and timers, LED drivers and industrial controls.
Parametrics
LNK304GN absolute maximum ratings: (1)DRAIN Voltage: -0.3 V to 700 V; (2)Peak DRAIN Current: 1400 mA (2600 mA); (3)FEEDBACK Voltage: -0.3 V to 9 V; (4)FEEDBACK Current: 100 mA; (5)BYPASS Voltage: -0.3 V to 9 V; (6)Storage Temperature: -65 ℃ to 150 ℃; (7)Operating Junction Temperature: -40 ℃ to 150 ℃; (8)Lead Temperature: 260 ℃.
Features
LNK304GN 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 1 mH inductor for up to 120 mA output current; (5)Tight tolerances and negligible temperature variation; (6)High breakdown voltage of 700 V provides excellent input surge withstand; (7)Frequency jittering dramatically reduces EMI (~10 dB)-minimizes EMI filter cost; (8)High thermal shutdown temperature (+135℃ minimum).
