Common features of U6101 and U6201 switching power management chips:
1. The primary side constant current technology can support discontinuous mode and continuous mode;
2. ±5% constant current accuracy, ±1% constant voltage accuracy;
3. Standby power consumption <75mW;
4. Fixed 65KHz switching frequency;
5. Green power saving mode and hiccup mode work;
6. Ultra-low starting and working current;
7. Integrated frequency jittering function to optimize EMI;
8. Integrated current mode control with internal slope compensation;
9. Constant current technology integrating line voltage and inductance compensation;
10. Integrated protection function of self-recovery mode.
The difference between U6101 and U6201 switching power management chips lies in the package pins. The U6101 chip can be packaged in SOP-8 and DIP-8, and the U6201 chip package is SOT-23-6.
