| Market Reality | The LinkSwitch-XT row (LNK362/363/364) is the sub-10-watt offline switcher of standby supplies, small adapters and the auxiliary rails inside bigger equipment: a 700V integrated MOSFET with self-powered ON/OFF control, 132kHz with jitter, and power tables running from about 2.8W to 9W - all in the DIP-8/SMD-8 body the whole industry recognizes. The substitution story is honest and local: the three family members interchange as a MATCHED SET with a design check (the drain current limit moves from the 200mA class to the 400mA class between rungs, and Power Integrations own guidance is to re-run the magnetics), while the two name neighbors - the LinkSwitch-TN parts (LNK30x) and the TinySwitch line - are different circuits that share only the brand. | The TinySwitch-III row is the power supply of an ocean of adapters, chargers, LED drivers and appliance supplies: one 700V MOSFET, a controller, and a feedback scheme simple enough for a five-component design. The family runs TNY274 to TNY280 as a power ladder - 6W to 20W adapter duty at 230V, halved on universal input - with identical pinouts and one of the most useful easter eggs in power integration: the bypass capacitor value selects the current limit, letting one board cover two adjacent rungs. Buyers get this family wrong in one direction only: fitting a smaller member where the load needs the larger, which shows up as start-up hiccups and thermal shutdown, not as a dead board. |
