Power Factor correction (PFC) is a major technological advancement in generating and using electrical power in an efficient way. It is used to improve the power quality, reduce power losses and to reduce the size and weight of electrical systems. The NCP1611BDR2G is an integrated power factor controller (IPFC) which is designed to simplify the implementation of feedback controlled boost PFC converters. NCP1611BDR2G provides comprehensive protection features and average current PFC control to maximize system performance, minimize external components and minimize cost.

NCP1611BDR2G is an integrated DC-DC boost PFC controller, which is used to improve the power factor and system efficiency of power conversion applications. It provides an effective 200 kHz fixed frequency, analog PFC control for boost converters, which helps to reduce hardware and board area by eliminating the need for complicated analog PFC design. It includes an internal digital-controlled oscillator (ECO) for controlling the switching frequency, and a cycle-by-cycle current limiting is also provided.

The NCP1611BDR2G operates in one of three control modes: (1) Continuous Conduction Mode (CCM); (2) Discontinuous Conduction Mode (DCM) and (3) Low Power Factor Mode (LPFM). All three can operate in open loop fashion with fast load step response. The LPFM mode gives precision control with the maximum power factor, while the CCM and DCM are suitable for operation with constant load current. The NCP1611BDR2G provides a speed up function to accelerate the power factor adjustment in all modes. In addition, a programmable soft start pin and a current sensing with high accuracy and low power consumption are also available.

The NCP1611BDR2G provides a wide range of protection features, including: under-voltage lockout (UVLO), over-current protection (OCP), open-loop protection, frequency jittering and cycle-by-cycle current limitation. These features help to ensure that the power conversion system remains safe and reliable. The NCP1611BDR2G also has a low power standby mode, which helps to reduce power consumption. In addition, it offers flexibility for various system configurations through a range of programmable parameters which customers can modify.
