PFC Section
● IEC 1000-3 compliant
● Additional operation mode as auxiliary power supply
● Fast, soft switching totem pole gate drive (1A)
● Dual loop control (average current and voltage sensing)
● Leading edge triggered pulse width modulation
● Peak current limitation

● Trailing edge triggered pulse width modulation
● Topologies of PWM converter are feed forward or flyback
● 50% maximum duty cycle to prevent transformer saturation
● fPWM=fPF
Special Features
● High power factor
● Typical 50μA start-up supply current
● Low quiescent current (15mA)
● Undervoltage lockout with internal stand-by operation
● Internally synchronized fixed operating frequency ranging from 15 kHz to 200 kHz
● External synchronization possible
● Shutdown of both outputs externally triggerable
● Peak current limitation
● Overvoltage protection
● Average current sensing by noise filtering
General Remarks
The TDA 16888 comprises the complete control for power factor controlled switched mode power supplies. With its PFC and PWM section being internally synchronized, it applies for off-line converters with input voltages ranging from 90 V to 270 V.
While the preferred topologies of the PFC preconverter are boost or flyback, the PWM section can be designed as forward or flyback converter. In order to achieve minimal line current gaps the maximum duty cycle of the PFC is about 94%. The maximum duty cycle of the PWM, however, is limited to 50% to prevent transformer saturation.
