Description: | BiCMOS PFC/PWM Combination Controller |
Manufacturer: | Texas Instruments |
Datasheet: | PDF (580K). Click here to download *) |
The UCC2850x family provides all of the control functions necessary for an active power-factorcorrected preregulator and a second-stage dc-to- dc converter. The controller achieves near-unity power factor by shaping the ac input line current waveform to correspond to the ac input-line voltage using average current-mode control. The dc-to-dc converter uses peak current-mode control to perform the step-down power conversion. |
