Overview
The INN3877C-H801-TL is an AC-DC converter from the InnoSwitch3-PD series, utilizing PowiGaN technology. It features a flyback topology with secondary side synchronous rectification and an internal switch rated at 725V breakdown voltage. Designed for universal input (85-265 VAC), it delivers up to 45 W output power. The device operates within a temperature range of -40°C to +105°C and includes comprehensive fault protection mechanisms such as overcurrent, overload, overtemperature, overvoltage, short circuit, and UVLO.
Feature Summary
- Integrates PowiGaN technology with an internal 725V switch for high-efficiency power conversion.
- Employs secondary side synchronous rectification to minimize conduction losses.
- Provides complete integrated protection against electrical faults including overvoltage and short circuits.
Applications
- Universal input AC-DC power supplies
- Adapters and chargers for consumer electronics
- Industrial control system power modules
Procurement Notes
Verify component authenticity through authorized Power Integrations distributors or certified partners. Confirm package integrity upon receipt, as the InSOP-24D package requires proper handling to prevent damage. Ensure compliance with RoHS3 specifications and check moisture sensitivity levels before soldering. Validate part markings against official datasheets to avoid counterfeit risks.
Selection Notes
Select this component for designs requiring isolated flyback conversion with integrated GaN switches. It is suitable for applications needing high power density and efficiency without external gate drivers. Consider the 725V rating for appropriate transformer design. Evaluate thermal management requirements given the 105°C operating limit and internal power dissipation characteristics.
Part Context
This part belongs to the InnoSwitch3-PD family, which combines primary-side regulation concepts with secondary-side synchronous rectification using Gallium Nitride technology. The series targets high-performance offline power supplies where size and efficiency are critical constraints.
Replacement Considerations
INN3879C-H801-TL offers similar functionality with different power ratings and switching frequencies. Verify pin compatibility and thermal performance when substituting.
