Package
Overview
It is a dedicated flow-driven control chip.
By using proprietary primary flow control technology, As a result, the system architecture has been streamlined to the greatest extent. It not only eliminates the optocoupler feedback device required for traditional secondary-side control, but also further eliminates the auxiliary winding used to achieve feedback in the traditional primary-side control architecture. Passive components such as feedback resistors and electrical rectifier diodes greatly reduce system costs. Due to the use of high-voltage direct power supply and current binning function, the output voltage and current range of the system are greatly broadened
The same drive system does not need to adjust the transformer
Drive~ pcs are connected in series, and the output current can be adjusted arbitrarily within the range, which is convenient for the application of series models.
Integrated complete protection functions, including cycle-by-cycle overcurrent protection for the input current
, open circuit protection for the current detection pin,
over-temperature protection, and Open-circuit and short-circuit protection on output.
