Application Notes

  • PFC Family Differences UCC3817A/18A/19A and UCC3817/18/19
    PDF, 32 Kb, File published: Aug 18, 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 Kb, File published: Nov 3, 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 Kb, File published: Jan 25, 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.
