LIS8716 isolation low PF (13-18W) has fun in July and is hot coming

.

It is a control chip dedicated to
constant current drive. Through patented digital current loop control technology and patented system architecture, the power system has been streamlined to the greatest extent. On this basis, it has demonstrated a powerful current regulation function. Without changing its peripheral devices, a wide range of current regulation can be achieved with only an external resistor without affecting the air conditioner. The consistency of load protection voltage. Due to the unique current adjustment technology, it can be directly used with external devices such as thermistors and photoresistors to form a feedback system for the external environment and output current, which can more effectively improve the reliability design and energy-saving characteristics of the entire lamp. At the same time, we have made optimal processing in terms of processing, anti-interference and solutions, providing perfect solutions for users to design high-end models. Based on patented power supply and adoption technology, the system adopts a patented three-stage working method, which can adaptively respond to differences in lamp bead voltage, and has a very wide output voltage and output current range. The same drive system can operate up to The driver~
chips are connected in series
to facilitate the application of series models. The following figure shows the typical application of this chip.
It also integrates complete protection functions, including cycle-by-cycle overcurrent protection of the input current, open circuit protection of the current detection pin,
overtemperature protection, and open circuit and short circuit protection of the output end.
