| FEATURES | |
| ?Variable Switching Frequency Control | DESCRIPTION |
| ?Programmable Minimum Switching Frequency With 4% Accuracy (3% accuracy at temperature range: -20� to 105�) ?Programmable Maximum Switching Frequency ?Programmable Dead Time for Best Efficiency | The UCC25600 high performance resonant mode controller is designed for dc-to-dc applications utilizing 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 |
| ?Programmable Soft-Start Time | package. Switching to the UCC25600 will greatly |
| ?Easy ON/OFF Control ?Over-Current Protection ?Over-Temperature Protection | simplify the system design, layout and improve time to market, all at a price point lower than competitive 16-pin device offerings. |
| ?Bias Voltage UVLO and OVP ?Integrated Gate Driver With 0.4-A Source and 0.8-A Sink Capability ?Operating Temperature Range: ?0� to 125� ?SOIC 8-Pin Package | 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 |
| programmable dead time enables zero-voltage | |
| APPLICATIONS | switching with minimum magnetizing current. This will |
| ?100-W to 1-kW Power Supplies ?LCD, Plasma and DLP?TVs ?Adaptors, Computing and ATX Power Supplies | maximize system efficiency across a variety of applications. The programmable soft-start timer maximizes design flexibility demanded by the varied requirements of end equipments utilizing a half bridge |
| ?Home Audio Systems ?Electronic Lighting Ballasts | topology. By incorporating 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 over current, UVLO, bias supply | |
| OVP and over temperature protection. |
