Description
The TDA 4862 is excellent convenient for designing a preconverter in ballasts and switched mode power supplies with sinusoidal line current consumption and a power factor approaching unity.

FEATUREs
• IC for sinusoidal line-current consumption
• Power factor approaching 1
• Controls boost converter as an active
   harmonics filter
• Internal start-up with low current consumption
• Zero current detector for discontinuous
   operation mode
• High current totem pole gate driver
• Trimmed ± 1.4% internal reference
• Undervoltage lock-out with hysteresis
• Very low start-up current consumption
• Pin compatible to world standard
• Fast overvoltage regulator
• Current sense input with internal low pass filter
