SLUUCS6A february 2023 – august 2023 UCC14340-Q1 , UCC14341-Q1
This user's guide provides a description as well as directions for use of the UCC14341EVM-069 to evaluate the UCC14341-Q1, high frequency, integrated transformer, DC-DC converter module from Texas Instruments. The EVM comes with UCC14341-Q1 populated by default but can also accommodate UCC14340-Q1. UCC14341-Q1 and UCC14340-Q1 are pin-to-pin compatible and functionally equivalent. All performance data and waveforms shown within this document were obtained testing the UCC14341-Q1. This EVM allows designers to quickly and efficiently evaluate the UCC14341-Q1 for use in automotive or industrial applications requiring gate driver IC bias power as high as 1.5 W, meeting up to 5-kVRMS isolation.
The user's guide can accompany UCC14341EVM-069, HVP069, Rev E1 and Rev A. Rev E1 and Rev A are identical.

The UCC14341-Q1 is a high efficiency, low-emissions, 5 kVRMS Isolated DC-DC Converter capable of delivering 1.5-W of power. Since the UCC14341-Q1 provides isolated power in an integrated package, this allows systems to reduce cost and size by removing the need for separate isolated power supplies. The UCC14341-Q1 delivers class-leading efficiency in power conversion from the primary to the secondary side while removing the need for bulky external transformers or power modules commonly used in existing designs. This integration allows for minimal printed circuit board (PCB) area as well as decreased height profile.
The UCC14341-Q1 is the default IC used in the UCC14341EVM-069 but any of the alternate versions listed in Table 1-1 can be used for evaluation. Each of the component versions listed in Table 1-1 are pin-to-pin compatible, functionally equivalent, drop in replacements with respect to one another.
General Part Number | Orderable Part Number | Isolation/Surge/Working Voltage |
---|---|---|
UCC14341-Q1 | UCC14341QDWNQ1 | 5 kVRMS/10 kVPK/1 kVRMS |
UCC14340-Q1 | UCC14340QDWNQ1 | 3 kVRMS/6.5 kVPK/850 kVRMS |
If U1 replacement is required, then TI recommends to always use best practice soldering techniques. Techniques can include taking appropriate ESD precautions and having qualified personnel, skilled at surface mount soldering and board level rework, removing and installing U1. Visually verify the desired UCC1434x-Q1 component version is properly installed in the EVM. If rework on U1 has previously been performed, then visually verify correct orientation of U1 according to Figure 1-1. The pin 1 identifying dot on top of the IC package is oriented at the top left according to Figure 1-1.
