LNK304GN

The LNK304GN is designed as one kind of lowest component count, energy-effi cient off-line switcher IC that can be used in wide range of applications such as (1)Appliances and timers; (2)LED drivers and industrial controls. And this device is specifi cally designed to replace all linear and capacitor-fed (cap dropper) non-isolated power supplies in the under 360 mA output current range.

Features of the LNK304GN are:(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 simplifi ed 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); (8)minimizes EMI filter cost; (9)High thermal shutdown temperature (+135 minimum).

The absolute maximum ratings of the LNK304GN can be summarized as:(1)DRAIN Voltage: -0.3 V to 700 V;(2)FEEDBACK Voltage: -0.3 V to 9 V;(3)FEEDBACK Current: 100 mA;(4)BYPASS Voltage: -0.3 V to 9 V;(5)Storage Temperature: -65 °C to 150 °C;(6)Operating Junction Temperature: -40 °C to 150 °C;(7)Lead Temperature: 260 °C.
