Excel-based Calculator Tool for LLC design with UCC25600
UCC25600
- Variable switching frequency control
- Programmable minimum switching frequency with 4% accuracy (3% accuracy at temperature range: –20°C to 105°C)
- Programmable maximum switching frequency
- Programmable dead time for best efficiency
- Programmable soft-start time
- Easy ON and OFF control
- Overcurrent Pprotection
- Overtemperature protection
- Bias voltage UVLO and overvoltage protection
- Integrated gate driver with 0.4-A source and 0.8-A sink capability
- Operating temperature range: –40°C to 125°C
- SOIC 8-Pin package
The UCC25600 high performance, resonant mode controller is designed for dc-to-dc applications using resonant topologies, especially the LLC half-bridge resonant converter. This highly integrated controller implements frequency modulation control and complete system functions in only an 8-pin package. Switching to the UCC25600 will greatly simplify the system design and layout, and improve time to market, all at a price point lower than competitive 16-pin device offerings.
The internal oscillator supports the switching frequencies from 40 kHz to 350 kHz. This high-accuracy oscillator realizes the minimum switching frequency limiting with 4% tolerance, allowing the designer to avoid over-design of the power stage and, thus, further reducing overall system cost. The programmable dead time enables zero-voltage switching with minimum magnetizing current. This maximizes system efficiency across a variety of applications. The programmable soft-start timer maximizes design flexibility demanded by the varied requirements of end equipment using a half-bridge topology. By incorporating a 0.4-A source and 0.8-A sink driving capability, a low cost, reliable gate driver transformer is a real option.
The UCC25600 delivers complete system protection functions including overcurrent, UVLO, bias supply OVP, and overtemperature protection.
