AN-6093 — Design Guideline for Flyback Charger Using FAN104WMX

More than half of the external power supplies produced are used for portable electronics, such as: smart phones, tablets, and MP3 players that require constant output voltage and current regulation for battery charging. For applications requiring precise Constant-Current (CC) regulation, current sensing in the secondary side is always necessary, which results in sensing loss. For power supply d...

Design Guideline of Single-Stage Flyback AC-DC Converter Using FAN7530 for LED Lighting

Analysis and Design of Self-Oscillating Flyback Converter

The self-oscillating flyback converter is a popular circuit for cost-sensitive applications due to its simplicity and low component count. It is widely employed in mobile phone chargers and as the stand-by power source in off-line power supplies for data-processing equipment. However, the optimization of this circuit is almost exclusively performed by a cutand-try approach since its operation i...

Design Guideline of Single-Stage Flyback AC-DC Converter Using FAN7530 for LED Lighting

This application note describes the single-stage power factor correction (PFC) and presents the design guidelines of a 75W universal-input, single-stage PFC for LED lighting applications. Flyback converter topology controlled by the critical conduction mode control IC, FAN7530 is applied and several functions; such as CV/CC mode feedback circuits, cycle-by-cycle current limit, soft-starting fun...
