LNK304PN IC – Power Integrations – AC-DC Off Line Switcher IC
₹94.00
The LNK304PN 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. LinkSwitch-TN devices integrate a 700 V power MOSFET, oscillator, simple On/Off control scheme, a high-voltage switched current source, frequency jittering, cycle-by-cycle current limit Figure 1. Typical Buck Converter Application (See Application Examples Section ? ?for Other Circuit Configurations).and thermal shutdown circuitry onto a monolithic IC. The start-up and operating power are derived directly from the voltage on the DRAIN pin, eliminating the need for a bias supply and associated circuitry in buck or fly back converters. The fully integrated auto-restart circuit in the LNK304 safely limits output power during fault conditions such as short-circuit or open loop, reducing component count and system-level load protection cost. ?A local supply provided by the IC allows use of a non-safety graded optocoupler acting as a level shifter to further enhance line and load regulation performance in buck and buck-boost converters.

TNY280PN IC - TinySwitch?-III energy-efficient, off-line switcher with enhanced flexibility and extended power range that incorporates a 700V power MOSFET, oscillator, high-voltage switched current source, current limit (user selectable), and thermal shutdown circuitry. The IC family uses an ON/OFF control scheme and offers a design flexible solution with a low system cost and extended power capability. The application includes chargers/adapters for cell/cordless phones, PDAs, digital cameras, MP3/portable audio, shavers, PC standby and other auxiliary supplies, DVD/PVR, and other low-power set-top decoders, supplies for appliances, industrial systems, and metering. ON/OFF control provides constant efficiency down to a very light load and it is ideal for mandatory CEC regulations and 1W PC standby requirements. Very low component count enhances reliability and enables a single-sided printed circuit board layout. High bandwidth provides fast turn-on with no overshoot and excellent transient load response.
