Overview

The UCC12040DVEG4 is a high-efficiency, 3-kVrms basic isolated DC/DC converter with integrated transformer technology. It is designed to provide up to 500 mW of isolated power to drive gate drivers, digital isolators, or interfaces like CAN and RS-485 in a compact, low-profile SOIC package.

Why Choose This Part

This device eliminates the need for an external transformer, significantly reducing PCB area and simplifying electromagnetic interference management. Its integrated proprietary technology achieves high efficiency while maintaining a low-profile 10.3mm x 10.3mm footprint with 2.65mm height.

Applications

Isolated Interface Power
Providing power to the secondary side of isolated CAN, RS-485, or I2C transceivers in industrial automation.
Gate Driver Bias Supply
Generating isolated bias rails for IGBT or SiC gate drivers in power electronics and motor drives.
Battery Management Systems
Supplying isolated power to cell monitoring ICs in high-voltage EV battery stacks.
Isolated Sensor Modules
Powering signal conditioning circuitry and ADCs in high-side current sensing applications.

Getting Started

Engineers should evaluate the part using the UCC12050EVM-022 evaluation module, which demonstrates the UCC12050/40 series performance. Pay close attention to the PCB layout guidelines regarding the 'stitching capacitor' formed by internal PCB layers to minimize EMI and ensure compliance with CISPR 32 Class B standards.
