TDA4817 Datasheet - Siemens Semiconductor

TDA4817 Power Factor Controller

This device has a conditioning circuit for the internal power supply. It allows standby operation with very low current consumption (less than 0.5 mA), a hysteresis between enable and switch-off levels and an internal voltage stabilization. An integrated Z-diode limits the voltage on VS, when impres.

TDA4817 Features

* IC for sinusoidal line-current consumption Power factor approaching 1 Controls boost converter as an active harmonics filter Direct drive of SIPMOS transistor Zero crossing detector for discontinuous operation mode with variable frequency q 110/220 V AC operation without switchover q Standby current
