Product Summary

The TDA16888 is a High Performance Power Combi Controller. The TDA16888 comprises the complete control for power factor controlled switchedmode power supplies. With its PFC and PWM section being internally synchronized, itapplies 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 linecurrent gaps the maximum duty cycle of the PFC is about 94%. The maximum duty cycleof the PWM, however, is limited to 50% to prevent transformer saturation.

Parametrics

TDA16888 absolute maximum ratings: (1)VCC supply voltage: -0.3 to VZ3V; (2)ROSC voltage: – 0.3~8V; (3)SYNC voltage: – 0.3~8V; (4)PFC FB voltage: – 0.3~8V; (5)PFC IAC voltage: – 0.3~15V; (6)AUX VS voltage:– 0.3~8V; (7)Junction temperature:– 40~150℃.

Features

TDA16888 features: (1)IEC 1000-3 compliant; (2)Additional operation mode as auxiliary power supply; (3)Fast, soft switching totem pole gate drive (1 A); (4)Dual loop control (average current and voltage sensing); (5)Leading edge triggered pulse width modulation; (6)Peak current limitation; (7)Topologies of PFC preconverter are boost or flyback; (8)Continuous/discontinuous mode possible; (9)94% maximum duty cycle.
