This document introduces the technical data of a high-performance power combi controller named TDA 16888, including the features and characteristics of the PFC (Power Factor Correction) section and the PWM (Pulse Width Modulation) section. The PFC section complies with the IEC 1000-3 standard and has an additional operation mode as an auxiliary power supply, fast and soft switching totem pole gate drive (1 A), dual loop control, leading edge triggered pulse width modulation, peak current limitation, boost or flyback topologies for the PFC preconverter, continuous or discontinuous mode possible. The PWM section features improved current mode control, fast and soft switching totem pole gate drive (1 A), soft-start management, trailing edge triggered pulse width modulation, feed forward or flyback topologies for the PWM converter, maximum duty cycle of 50% to prevent transformer saturation, external synchronization possible. In addition, the product has high power factor, typical 50 µA start-up supply current, low quiescent current (15 mA), undervoltage lockout with internal stand-by operation, internally synchronized fixed operating frequency ranging from 15 kHz to 200 kHz, external synchronization, shutdown of both outputs externally triggerable, peak current limitation, overvoltage protection, average current sensing by noise filtering, etc.
The TDA16888 is a high‑performance power combi controller that integrates PFC and PWM sections with dual‑loop control, soft‑switching gate drive, and a wide operating frequency range. It supports input voltages from 90 V to 270 V and offers features such as high power factor, low quiescent current, and built‑in protection circuits.
The datasheet provides detailed pin definitions, functional descriptions, protection mechanisms, oscillator synchronization, and package outlines for both DIP and SO packages, enabling designers to implement the IC in offline converters and auxiliary power supplies.
