Manufacturer:AMD Description: The control algorithm utilized by the UCC3888 sets the switch on time inversely Output Sinks 200mA, Sources proportional to the input line voltage and sets the switch off time inversely propor- 150mA Into a MOSFET Gatetional to the output voltage. This action is automatically controlled by an internal Uses Low Cost SMD Inductors feedback loop and reference. The cascaded configuration allows a voltage conver- sion from 400V to 2.7V to be achieved with a switch duty cycle of 7.6%. This topol- Short Circuit Protectedogy also offers inherent short circuit protection since as the output voltage falls to zero, the switch off time approaches infinity. Optional Isolation Capability The output voltage is set internally to 5V. It can be programmed for other output voltages with two external resistors. An isolated version can be achieved with this topology as described further in Unitrode Application Note U-149. |
