The XP3323 is a high performance CrM power factor correction (PFC) IC for boost power topologies. X-Signal's patented digital power control algorithms enable the XP3323 to deliver industry-leading dynamic performance and light-load PF/THD performance to meet worldwide certification and safety requirements, and the XP3323 is primarily intended for power factor correction of solid state lighting (SSL) or AC/DC power supplies.
01 Product Features
■ Supports full voltage AC input (90VAC - 305VAC) up to 300W.
■ Field configurable BUS voltage follower outputs or fixed outputs with a variety of minimum clamp levels.
■ More than 33% of the load to meet the PF > 0.9, THD < 20%, large margin to meet the IEC61000-3-2 harmonic requirements
■<70mW no-load power consumption, and PFC shutdown function to achieve lower standby power requirements
■ Patented digital control technology to achieve industry-leading dynamic performance, dynamic BUS voltage <±5% overshoot
■ With the function of analysing the back-end DC/DC feedback (FB) signal, automatically starting and stopping the PFC according to the back-end load status.
■ OLP accuracy <± 5% over full voltage range
■ SOP8 package
