Power factor correction (PFC) formula is fundamental in modern power supply designs. PFC converter regulation ensures an optimal energy efficiency of a system. Power management integrated circuit (PMIC) NCP1603D100R2G provides an effective way for implementation of PFC. It is specifically designed for digital power systems and provides a high level of integration, accurate current and voltage management, fault protection, and precise output power control.

NCP1603D100R2G features a switching frequency of 20kHz, adjustable DC/DC current limit and pre-bias start-up voltage. It integrates a High-Side mode PFC controller and a dual output, adjustable single ended or bridges mode second stage driver. The PMIC also has a power path system with a wide dynamic regulation range for fast transient response for the input and output capacitors.

The IC is suitable for a wide range of input voltages from 25V to 500V, and operates from -40°C to 85°C. It also provides an extensive protection system, including an adjustable over-power/current protection, overload protection, and over-temperature protection. NCP1603D100R2G can be used in various high-power electrical applications such as server power supplies and distributed power systems.

The main working principle of power factor correction is the adjusting of the phase angle of the current waveform in order to eliminate harmonics, improve power conversion efficiency and minimize reactive power. This phase angle is achieved by the PFC circuit that compensates the waveform by injecting a controllable electrical current into the load continuously and in phase. This current causes the voltage waveform of the output rectifier to be in-phase with the AC mains and prevent the current waveform from lagging behind.

The NCP1603D100R2G is an advanced, integrated, PFC control unit that reduces the design and implementation complexity of power factor conversion circuits. The integrated PFC controller has a full-digital compensator and operates in Current Mode PFC. Its design eliminates external limiting and compensator components, and the programming of the PMIC enables it for quick response to system and load changes.

The IC’s wide output voltage, high efficiency, protection functions, and optional controller extensions for standalone 3-phase operation make it an ideal choice for many power supply designs. With NCP1603D100R2G, engineers can create sophisticated, efficient and reliable power supplies while reducing their development costs and design time.
