This highly integrated controller Range: –20°C to 105°C) implements frequency modulation control and • Programmable Maximum Switching Frequency complete system functions in only an 8-pin package. Switching to the UCC25600 will greatly simplify the • Programmable Dead Time for Best Efficiency system design and layout, and improve time to • Programmable Soft-Start Time market, all at a price point lower than competitive 16- • Easy ON and OFF Control pin device offerings. • Overcurrent Protection The internal oscillator supports the switching • Overtemperature Protection frequencies from 40 kHz to 350 kHz. This high- • Bias Voltage UVLO and Overvoltage Protection accuracy oscillator realizes the minimum switching frequency limiting with 4% tolerance, allowing the • Integrated Gate Driver With 0.4-A Source and 0.8- designer to avoid over-design of the power stage A Sink Capability and, thus, further reducing overall system cost. The • Operating Temperature Range: –40°C to 125°C programmable dead time enables zero-voltage • SOIC 8-Pin Package switching with minimum magnetizing current. This maximizes system efficiency across a variety of applications. The programmable soft-start timer 2 Applications maximizes design flexibility demanded by the varied • 100-W to 1-kW Power Supplies requirements of end equipment using a half-bridge • LCD, Plasma, and DLP® TVs topology. By incorporating a 0.4-A source and 0.8-A sink driving capability, a low cost, reliable gate driver • Adaptors, Computing, and ATX Power Supplies transformer is a real option. • Home Audio Systems The UCC25600 delivers complete system protection • Electronic Lighting Ballasts functions including overcurrent, UVLO, bias supply OVP, and overtemperature protection.
