PFS7525L集成电路（IC）的PFC（功率因数校正）规格书PDF中文资料

Key Benefits

• High efficiency and power factor across load range

• >95 efficiency from 10 load to full load

• <60 mW no-load consumption at 230 VAC

• PF >0.92 easily achievable at 20 load

• EN61000-3-2 Class C and D compliant

• Highly integrated for smallest boost PFC form factor

• Integrated controller, MOSFET and ultra-low reverse recovery loss

diode (Qspeed)

• Packaging optimized for high volume production

• Eliminates insulating pad/heat-spreader

• Enhanced features

• Programmable Power Good (PG) signal

• User selectable power limit: Enables different HiperPFS-3 family

members to be tested in the same design for optimum device

selection

• Integrated non-linear amplifier for fast output OV and UV

protection and transient response

• Digital line peak detection that provides robust performance even

with distorted input voltage from UPS or generators

• Digital power factor enhancer compensates for EMI filter and

bridge distortion, providing high-line PF >0.92 @ 20 load

• Frequency adjusted over line voltage and each line cycle

• Spread-spectrum across >60 kHz window simplifies EMI filtering

requirements

• Lower boost inductance

• Provides up to 450 W peak output power for universal

applications, 1 kW for high-line only applications

• Protection features include: UVLO, UV, OV, OTP, brown-in/out,

cycle-by-cycle current limit and power limiting for overload

protection

• Halogen free and RoHS compliant
