This highly integrated • Programmable Maximum Switching Frequency controller implements frequency modulation control • Programmable Dead Time for Best Efficiency and complete system functions in only an 8-pin • Programmable Soft-Start Time package. Switching to the UCC25600 will greatly simplify the system design, layout and improve time • Easy ON/OFF Control to market, all at a price point lower than competitive • Over-Current Protection 16-pin device offerings. • Over-Temperature Protection The internal oscillator supports the switching • Bias Voltage UVLO and OVP frequencies from 40 kHz to 350 kHz. This high • Integrated Gate Driver With 0.4-A Source and accuracy oscillator realizes the minimum switching 0.8-A Sink Capability frequency limiting with 4% tolerance, allowing the • Operating Temperature Range: –40°C to 125°C designer to avoid "over design" of the power stage • SOIC 8-Pin Package and, thus, further reducing overall system cost. The programmable dead time enables zero-voltage switching with minimum magnetizing current. This will APPLICATIONS maximize system efficiency across a variety of • 100-W to 1-kW Power Supplies applications. The programmable soft-start timer • LCD, Plasma and DLP ® TVs maximizes design flexibility demanded by the varied • Adaptors, Computing and ATX Power Supplies requirements of end equipments utilizing a half bridge topology. By incorporating 0.4-A source and 0.8-A • Home Audio Systems sink driving capability, a low cost, reliable gate driver • Electronic Lighting Ballasts transformer is a real option. The UCC25600 delivers complete system protection functions including over current, UVLO, bias supply OVP and over temperature protection.
