TNY268PN Power Integrations TinySwitch-II 700V Offline Switcher IC DIP-8B

The TNY268PN from Power Integrations is a TinySwitch-II series energy-efficient low-power offline switcher IC designed for compact flyback AC-DC power supplies. It integrates a 700V high-voltage power switch and control circuitry, helping reduce external component count, simplify power supply design and minimize overall system size.

Operating at 132kHz, TNY268PN helps reduce transformer size and incorporates frequency jittering to significantly lower EMI. Integrated features include auto-restart protection for short-circuit and open-loop faults, programmable line undervoltage detection, current limiting and over-temperature protection for improved system reliability.

Supplied in a through-hole DIP-8B package, TNY268PN supports up to 23W open-frame output at 230VAC and up to 15W open-frame output over the universal 85–265VAC input range. It is suitable for mobile device chargers, low-power adapters, PC and TV standby supplies, DVD players, set-top boxes, home appliances and embedded auxiliary power supplies.
