Description
Specially designed for LED driving lighting constant current power supply chip, suitable for voltage input range (AC176V~AC265V) non-isolated step-down constant current power supply scheme. Built-in high-precision current regulation module, integrated high-precision constant current output module and line voltage adjustment module, to achieve the whole power supply program output current does not change with the change of inductance and LED working voltage. High-performance power tubes are integrated into the chip, and the current detection current is used to ensure that the chip's power consumption is extremely low. The chip has very few peripheral components, which largely reduces the design difficulty and reduces the size of the system, and greatly reduces the production cost for customers. The chip is safe and reliable, comes with output open circuit protection and short circuit protection, CS resistor short circuit
