PFC Controllers Outfit Wide Range Of Supplies

The NCP1653 and NCP1601 PFC controllers target power supplies with input levels between 75W and several kilowatts. The NCP1653 is a fixed-frequency, current-mode controller for driving continuous conduction mode boost converters with power levels from 100W to 3 kW. It also operates with the output voltage tracking the input voltage. Other features include: average current-mode or voltage-mode control; soft-start; under-voltage lockout; under-voltage, over-voltage and over-power protection; and thermal shutdown. The NCP1601, for PFC boost circuits up to 300W, operates in either fixed-frequency discontinuous conduction mode (DCM) and/or variable frequency critical conduction. In DCM mode, it can synchronize to an external frequency source or set at a fixed frequency. Prices for the NCP1653 and NCP1601 are $0.66 and $ 0.36 each/10,000, respectively.
