The INN4073C-H186-TL from Power Integrations is an InnoSwitch™4-CZ offline Flyback controller with an integrated switch and 750V breakdown voltage. It delivers up to 70W at 140kHz switching frequency, featuring EN, Frequency Control, and Soft Start. Integrated protections include Current Limiting, Over Temperature, Over Voltage, and Short Circuit. It is housed in a 24-PowerSMD module package rated for -40°C to 105°C (TA).
- 750V breakdown voltage provides margin for offline Flyback designs.
- Integrated switch simplifies the power stage and reduces external components.
- 70W power capability at 140kHz supports higher-power isolated supplies.
- Integrated protections (Current Limiting, Over Temperature, Over Voltage, Short Circuit) enhance reliability.
- EN, Frequency Control, and Soft Start offer flexible control and reduced start-up stress.
