TDA16888
Key Features
- 2 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.
