ATC9501 Power Supply Control IC Anachip

 

Description

The ATC9501 is suitable for low cost, high precision constant current (CC / CV) applications. Constant current constant voltage ring without optocoupler, TL431 and compensation circuit, the internal integration of 900V power tube, reducing system cost.

ATC9501 can meet the output voltage ± 5% of the production accuracy. Very low start-up current, quasi-valley detection can easily meet EPA2.0 energy efficiency requirements. Output voltage compensation cable can be adjusted according to customer requirements, greatly facilitate the customer’s system design.

ATC9501 also integrates a variety of protection features: undervoltage lockout, leading edge blanking, overvoltage protection, overcurrent protection, loop open circuit protection, output short circuit protection, greatly increasing the stability of the system.
