TNY288PG switching power supply chip

Description:
The TNY288PG is a highly integrated switching power supply IC designed for low-power applications. It is part of the TinySwitch-III family, which combines a high-voltage power MOSFET, oscillator, high-voltage switched current source, current limit, and thermal shutdown circuitry into a single monolithic IC. This integration significantly reduces the number of external components required, simplifying the design of compact, efficient, and reliable power supplies.
