| Title | HIGH PERFORMANCE CURRENT MODE CONTROLLERS |
| Description | Order this document by UC3844/D UC3844, 45 UC2844, 45 High Performance Current Mode Controllers The UC3844, UC3845 series are high performance fixed frequency current mode controllers. They are specifically designed for Off–Line and dc–to–dc converter applications offering the designer a cost effec. |
| Features |
consisting of input and reference undervoltage lockouts each with hysteresis, cycle –by –cycle current limiting, a latch for single pulse metering, and a flip –flop which blanks the output off every other oscillator cycle, allowing output deadtimes to be programmed for 50% to 70%. These devices are available in an 8 –pin dual –in –line plastic package as well as the 14 –pin plastic surface mount (SO –14).. |
