PFS7535H集成電路（IC）的PFC（功率因數(shù)校正）規(guī)格書PDF中文資料

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
