The INN3378C-H302-TL from Power Integrations is an isolated flyback offline switcher from the InnoSwitch™3-Pro PowiGaN™ family. It integrates a 725V switch, delivers up to 70 W at 70kHz, and operates from a 3.42V to 3.78V Vcc supply with a 5V start-up threshold. Current limiting, over temperature, over voltage, and short circuit protection are built in, and the 24-PowerSMD module supports -40°C to 105°C operation.
- Integrated 725V PowiGaN switch simplifies flyback design and reduces external component count.
- Galvanically isolated output ensures safe separation for offline AC-DC supplies.
- 70 W output at 70kHz balances power density and switching losses.
- Comprehensive fault protection (current limiting, OTP, OVP, SCP) improves reliability.
- Wide -40°C to 105°C range suits demanding industrial and consumer applications.
