LinkSwitch-TN 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

TNY268PN IC – Power Integrations Off Line Switcher with Low Power IC
TNY268PN IC - Low Power Off-Line Switcher - Power Integrations - DIP-8
The TNY268PN integrates a 700V power MOSFET, oscillator, high voltage switched current source, current limit, and thermal shutdown circuitry onto a monolithic device. The start-up and operating power are derived directly from the voltage on the DRAIN pin, eliminating the need for a bias winding and associated circuitry. In addition, the TNY268PN incorporates auto-restart, line under voltage sense, and frequency jittering. An innovative design minimizes audio frequency components in the simple ON/OFF control scheme to practically eliminate audible noise with standard taped/varnished transformer construction. The fully integrated auto-restart circuit safely limits output power during fault conditions such as output short circuits or open loop, reducing component count and secondary feedback circuitry cost.
TNY280PN IC – Power Integrations AC/DC Converter IC
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.
