Overview

NCP1654 is a power factor correction controller (PFC) designed to operate in fixed frequency, continuous conduction mode (CCM). Operating at a fixed frequency helps meet electromagnetic interference standards and limit radiated noise that may contaminate surrounding systems. In addition, the continuous conduction mode of operation reduces the application of di/dt and the resulting interference. More generally, NCP1654 is an ideal power factor correction driver (PFC) in systems where cost-effectiveness, reliability, and high power factor are key parameters. NCP1654 requires a minimum number of external components. In particular, this circuit solution simplifies the power factor correction circuit (PFC) design and eliminates the need for any input voltage detection. In addition, the circuit provides functions such as brown-out or true power limiting, optimizing the power factor correction circuit (PFC) design. NCP1654 continuously monitors the output voltage, inductor current, and junction temperature to protect the system from possible overstress. NCP1654 is optimized to achieve the smallest possible power loss in all operating modes. During the startup phase and in the shutdown mode, the current consumption is particularly small, so when the circuit is disabled, the power loss of the power factor correction circuit (PFC) is minimal. This feature helps meet more stringent low standby power consumption specifications. Simply grounding the feedback pin forces NCP1654 into shutdown mode. NCP1654 provides comprehensive protection, such as VDD undervoltage protection, soft start, overvoltage protection, inductor current limiting, brown-out detection, over-power limiting, overheat shutdown, etc.
