SP5610
The SP5610 is a high precision off-line switching power supply circuit for low power AC / DC charger with adapters. The original edge sampling SP5610 accurate constant current, constant voltage control, eliminates the need for general applications optocoupler and TL431.
In the constant current mode, set the output power by the CS pin external sampling resistor Rs. In constant voltage mode, a variety of operating modes of the chip can guarantee a higher overall conversion efficiency. In addition, the chip built-in cable drop compensation, and thus achieve good load regulation. SP5610 operate in PFM status in the constant current mode, constant voltage mode PWM state drop frequency operation at light load.
SP5610 provides power soft start function with a variety of self-recovery protection, including by-cycle current limit protection (OCP), VDD over-voltage protection (OVP), VDD over voltage clamp, undervoltage protection (UVLO), over temperature protection. SP5610 has a shake-frequency function, can provide better EMI performance.
