INN3947CQ0501-TL

Overview

The INN3947CQ0501-TL is an automotive-grade AC/DC converter from the InnoSwitch3-AQ series, manufactured by Power Integrations. It utilizes Silicon Carbide (SiC) technology in a flyback topology to deliver up to 35 W of output power. The device integrates a 1700 V switch and supports input voltages ranging from 40 V to 1.2 kV. Output voltage options span 5 V to 24 V. Operating parameters include a switching frequency between 25 kHz and 95 kHz. The component functions within a temperature range of -40 °C to +150 °C and is housed in an InSOP-T28G package.

Feature Summary

Integrates a 1700 V SiC MOSFET for high-voltage operation
Includes secondary-side regulation via FluxLink isolated feedback
Complies with AEC-Q100 automotive qualification standards

Applications

Auxiliary power supplies for traction inverters
Backup and bias power sources for DC-DC converters
On-board charger auxiliary circuits

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact electrical characteristics and packaging configuration. Confirm that the component meets the required automotive reliability standards for the intended application environment. Ensure compatibility with the target PCB footprint and thermal management requirements before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring high-efficiency conversion at elevated bus voltages. The integrated SiC switch reduces external component count compared to discrete solutions. Consider the wide input voltage range when designing for variable source conditions. Verify that the thermal performance of the InSOP-T28G package aligns with the system's heat dissipation capabilities under maximum load conditions.

Part Context

This part belongs to the InnoSwitch3-AQ family, designed specifically for automotive applications. The series combines primary and secondary controllers with safety-rated feedback into a single IC. This integration simplifies design complexity while maintaining high efficiency across the full load range. The AQ designation indicates compliance with automotive quality and reliability requirements.
