INN3949CQ-TL

Overview

The INN3949CQ-TL is an isolated AC/DC converter from the InnoSwitch3-AQ series, designed for automotive applications. It integrates a silicon switch with a breakdown voltage of 1700 V and utilizes FluxLink™ technology for primary-side regulation. The device supports a wide input voltage range of 40 V to 1200 V DC and delivers up to 70 W of output power. Key electrical parameters include a switching frequency of 132 kHz and a no-load supply current of 266 µA. It operates within a temperature range of -40 °C to +150 °C and is housed in an InSOP-24D package.

Feature Summary

Integrates a high-voltage silicon switch with primary-side control via FluxLink™ feedback
Supports wide input voltage ranges suitable for high-voltage DC-DC conversion
Optimized for high efficiency and compact design in automotive environments

Applications

Automotive DC-DC converters
Traction inverter auxiliary power supplies

Procurement Notes

Verify that the specific suffix 'CQ' corresponds to the required voltage rating and packaging configuration for your design. Confirm AEC-Q100 qualification status if automotive reliability is mandatory. Check for RoHS compliance details and ensure the InSOP-24D footprint matches your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when designing isolated power stages requiring high input voltages up to 1200 V DC. It is appropriate for systems needing integrated primary-side regulation without optocouplers. Consider the thermal performance of the InSOP-24D package and the 132 kHz switching frequency for EMI management in dense automotive layouts.

Part Context

This part belongs to the InnoSwitch3-AQ family, which provides integrated offline switcher ICs for flyback topologies. The series is characterized by high integration levels, combining power MOSFETs, controllers, and protection circuits into a single package to simplify design and reduce component count in switched-mode power supplies.
