2005-06-16 Transition-mode PFC controller enhances performance
Take a look at a controller IC that is based on standard TM PFC pre-regulator core and offers additional features
2000-06-19 L6569-L6561 lighting application with PFC
This application note has been developed to supply two 18W fluorescent lamps. It consists of two sections: a Power Factor Corrected (PFC) pre-regulator, using the L6561, and the lamp ballast stage with the L6569.
2003-12-01 Critical conduction PFC input filter design
This paper discusses a design option power supply engineers can apply to create a filter that cleans up noisy input currents in critical conduction offline PFC pre-regulator systems.
2010-09-15 100W transition-mode PFC pre-regulator with the L6563S
This application note describes a demo board based on the transition-mode PFC controller L6563S and presents the results of its bench demonstration
2010-09-15 100W transition-mode PFC pre-regulator with the L6563H
This application note describes a demo board based on the transition-mode PFC controller L6563H and presents the results of its bench demonstration
2000-06-20 L6561, enhanced transition mode power factor corrector
This application note implements the TM (Transition Mode) technique for the L6561 PFC pre-regulator in low-power applications, such as lamp ballasts and low-end monitors.
2013-06-13 Fairchild simplifies BLDC motor controller reference design
Reference design RD-401 uses SPM smart power modules and incorporates PFC to enable designers to simplify design, reduce BOM costs and develop rapid prototypes
2000-06-16 P.F.C. application ideas using mains transformer
This application note quantifies the effect of a PFC pre-regulator stage, connected to a typical dc/dc converter in terms of efficiency, harmonic content and apparent power (VA) drawn from the mains.
2006-06-29 ST unrolls controller for resonant half-bridge topology
STMicroelectronics introduced an advanced double-ended controller specifically designed for the series-resonant half-bridge topology.
2005-08-15 How power modules address unique appliance requirements
Thanks to the improved performance and efficiency they provide, the demand for inverterized drives and brushless DC (BLDC) motors continues to grow.
2013-04-19 Grasping power factor and solid state lighting
In order to effectively design an LED-based luminaire, designers need to understand power factor, the impact of LED drivers on it, and the different techniques for cost-effectively integrating power factor correction in the LED driver design.
2005-12-15 Controller IC tailored for single-ended switching power converters
STMicroelectronics announced a current-mode primary controller IC designed to build single-ended switching power converters.
