• Transformerless Off-line The UCC1889 controller is optimized for use as an off-line, low power, low voltage, Applications regulated bias supply.
The unique circuit topology utilized in this device can be • Ideal Primary-side Bias Supply visualized as two cascaded flyback converters, each operating in the discontinuous mode, and both driven from a single external power switch.
The significant • Efficient BiCMOS Design benefit of this approach is the ability to achieve voltage conversion ratios of 400V • Wide Input Range to 12V with no transformer and low internal losses.
