      Charger Adapter

      Charger case

      Juyuan micro has AC / DC power chip products with relatively complete power range in the field of charger. We can provide you with PSR series of 3-12w built-in BJT power tube, PSR series of 7.5-36w built-in MOS power tube and PSR models of external MOS power tube, and provide reference design scheme of adapater / charger system with high cost performance, excellent performance and stable quality.

      1、 Charger performance characteristics:

      1. High precision constant current / constant voltage regulation within the full voltage range;

      2. Remove optocoupler and secondary control circuit;

      3. Built in transformer inductance compensation;

      4. Low starting current, built-in soft start and undervoltage protection;

      5. Built in leading edge blanking and over temperature protection;

      6. Current limiting protection, overvoltage protection.
