Product details
Overview
UCC25660EVM-064 from Texas Instruments is a fully assembled, stand-alone evaluation module for the UCC25660x family of LLC resonant half-bridge DC-DC controllers. It implements a 180-W, 12-V output power stage with 365–410 VDC or 85–265 VAC input, featuring IPPC control, adaptive dead-time, X-capacitor discharge, and full protection suite including OCP, OVP, OTP, and UVLO.
For engineers reviewing the UCC25660EVM-064 datasheet, UCC25660EVM-064 test setup, UCC25660EVM-064 application notes, or UCC25660EVM-064 hardware design files, this EVM provides validated reference schematics, PCB layouts, BOM, thermal performance data, efficiency curves, loop response plots, and transient waveforms - all essential for rapid LLC topology validation and controller parameter tuning.
Technical Context
The UCC25660EVM-064 implements a resonant half-bridge LLC converter using the UCC256601DDBR controller in 16-pin SOIC package (with high-voltage pin removal), paired with IPB60R105CFD7ATMA1 600-V MOSFETs and STPS41H100CTY Schottky rectifiers. It supports both diode and synchronous rectification (via optional UCC24624 + SR FETs).
It operates across 365–410 VDC or 85–265 VAC inputs, delivers regulated 12 VDC at up to 15 A, achieves >92% peak efficiency, and incorporates programmable burst mode, audible-noise avoidance, capacitive-region avoidance, and adaptive soft-start - all verified under natural convection at 25°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 365–410 VDC or 85–265 VAC, 47–63 Hz - enables universal AC/DC front-end compatibility without external PFC stage |
| Output Rating | 12 VDC / 15 A / 180 W - sufficient for high-power industrial and consumer applications requiring stable low-voltage rail |
| Resonant Frequency | 88–126 kHz (measured 88.4–125.4 kHz across line/load) - dynamically adjusted by UCC25660x to maintain ZVS over wide operating range |
| Peak Efficiency | 92.44% at 390 VDC / 15 A - achieved via IPPC control, adaptive dead-time, and optimized gate drive timing |
| Standby Power | 51 mW at 0 mA output - meets DoE Level VI and EuP standby requirements using low-frequency burst and pulse-skipping modes |
| Thermal Performance | Max 86°C on D2 (output rectifier) at full load, no forced air - validates thermal design margin for enclosed industrial environments |
| Output Ripple | 120 mVpp at 390 VDC / 15 A - measured with AC-coupled oscilloscope, confirming low-noise regulation suitable for sensitive loads |

FAQ
What is the primary function of the UCC25660EVM-064?
The UCC25660EVM-064 is a complete, ready-to-use evaluation module for the UCC25660x LLC resonant controller family. It demonstrates a 180-W, 12-V half-bridge LLC converter with validated operation across 365–410 VDC or 85–265 VAC inputs. The UCC25660EVM-064 includes all necessary power components, test points, and documented startup/thermal/efficiency data - enabling immediate controller evaluation without custom board design.
Which controller IC is pre-installed on the UCC25660EVM-064?
The UCC25660EVM-064 ships populated with the UCC256601DDBR - a 16-pin SOIC-packaged LLC controller optimized for light-load efficiency and integrated high-voltage gate driver functionality. The UCC25660EVM-064 can be reconfigured for UCC256602 or UCC256603 variants via documented component swaps and jumper modifications per TI's User's Guide.
Does the UCC25660EVM-064 support synchronous rectification?
Yes - the UCC25660EVM-064 supports synchronous rectification as an optional configuration. Users can populate the UCC24624DR synchronous rectifier controller and associated SR FETs to replace the default diode rectifier (STPS41H100CTY). This upgrade improves full-load efficiency and reduces thermal stress on the secondary side, as confirmed in TI's implementation results.
What safety precautions apply when operating the UCC25660EVM-064?
The UCC25660EVM-064 is classified as a Texas Instruments High Voltage Evaluation Module (TI HV EVM) and operates with hazardous voltages (>365 VDC). Users must follow TI's HV EVM safety guidelines: de-energize before probing, use insulated tools, implement emergency power-off, maintain physical barriers, and never operate unattended. The board lacks internal fusing and relies on external current-limited sources for protection.
Where can I find the schematic, layout, and BOM for the UCC25660EVM-064?
The complete hardware design files for the UCC25660EVM-064 - including power/control schematics (Figures 4-1 and 4-2), top/bottom PCB layouts (Figures 4-3 and 4-4), and a detailed Bill of Materials (Table 4-1) - are provided in Section 4 of the official UCC25660EVM-064 User's Guide (SLUUCV2A). All files are publicly available on ti.com and include part numbers, footprints, and placement details for full design replication.
