High Speed Voltage Mode Pulse Width Modulator
Programmable Maximum Duty Cycle Clamp Optocoupler Interface 50-μA Start-Up Current 4.2-mA Operating Current@1 MHz Smallest Footprintof the 8-pin MSOPPackage Minimizes Board Area and Heightdescription
The UCC35705 and UCC35706 devices are 8-pin voltage mode primary side controllers with fast over-currentprotection. Thesedevices are usedas core high-speed buildingblocksin highperformanceisolated and non-isolatedpower converters.
UCC35705/UCC35706 devices featurea high speed oscillator with integrated feed-forward compensation forimproved converter performance.A typical current senseto output delay timeof 25ns provides fast responsetooverload conditions. TheIC also provides an accurate programmable maximum duty cycle clamp for increasedprotection which can alsobe disabledfor the oscillatorto runat maximum possible duty cycle.
Two UVLO options are offered. The UCC35705 with lower turn-on voltageis intendedfor dc-to-dc converters whilethe higher turn-on voltage and the wider UVLO rangeof the UCC35706is better suitedfor offline applications.
The UCC35705/UCC35706 familyis offeredin 8-pin MSOP (DGK), SOIC (D) and PDIP (P) packages.
