U-149 Elegantly Simple Off-Line Bias Supply for Very Low Power Applications
PDF, 328 Kb, File published: Sep 5, 1999
The UCC3889 controller is an off-line, low-power, low-voltage, regulated-bias power supply. The unique circuit topology in this device can be visualized as two cascaded flyback converters, each operating in the discontinuous mode, and both driven from a single external power switch. The significant benefit of this approach is voltage conversion ratios of 400V to 12V, with no transformer and low in
