ON Semiconductor, a global supplier of efficient power management solutions, announced the expansion of its industry portfolio of Power Factor Correction (PFC) controllers. Designed for use in lighting, adapters, ATX supplies, flat- panel TVs and other power applications, the four new devices enable the development of highly efficient power supplies that meet emerging global energy efficiency and power factor standards.
Andy Williams, senior vice president and general manager of the automotive and power regulation group, said, "The introduction of these devices extends ON Semiconductor's position in power factor controllers. The four new devices complement our existing PFC product portfolio by providing industry standard replacements with improved features, new and innovative control methods, and added functions that ease both the time and effort required to design highly efficient Switch Mode Power Supplies." he further added, "To address our customers' ongoing demand for ever more efficient power management, we will continue to develop PFC solutions targeted to meet their design challenges."
The new devices include NCP1605 an enhanced, high voltage and efficient standby mode power factor controller that can work in fixed frequency Discontinuous Conduction Mode (DCM) or/and in Critical conduction Mode (CRM). The NCP1606 series CRM power factor controllers designed for use as a pre-converter in electronic ballast, ac adapters.
The NCP1654 and NCP1655 are Continuous Conduction Mode power factor correction controllers that controls the power switch conduction time in a fixed frequency mode and in dependence on the instantaneous coil current. They also integrate high safety protection features like a brown-out function, an effective input power runaway clamping circuitry, and minimize the number of external components required for circuit implementation.
