  PFC Family Differences UCC3817A/18A/19A and UCC3817/18/19
  PDF, 32 Кб, Файл опубликован: 18 авг 2003
  The UCC3817A/18A/19A family of PFC controllers (UCC3817A family) is pin for pin compatible with the UCC3817/18/19 family of devices (UCC3817 family). The output stage of UCC3817A family has been updated to allow use of a smaller external gate drive resistor values. For some power supply designs where an adequately high enough gate drive resistor can not be used, the UCC3817A family offers a more r

  Synchronizing a PFC Controller from a Down Stream Controller Gate Drive
  PDF, 103 Кб, Файл опубликован: 3 ноя 2000
  Due to pending line harmonic requirements at higher power levels, power factor correction (PFC) is required in some ac-to-dc off-line power converter applications. This type of power converter can be designed with two cascaded power stages similar to the configuration in Figure 1. The first stage is a boost converter that converts the ac voltage to dc voltage with PFC. The output voltage of the bo

  Accurate PWM Duty Cycle Clamp
  PDF, 58 Кб, Файл опубликован: 25 янв 2002
  Power supply applications using current sense transformers require a duty cycle clamp on the pulse width modulator (PWM) to ensure transformer reset. Not all PWMs come with a duty cycle clamp presenting a problem for the power supply designer. This application note shows how to implement a duty cycle clamp by using a simple delay circuit.
