Detailed Product Description: | Shenzhen Senliweier Electronics Co., Ltd. Shenzhen Senliwell Electronics Co., Ltd. TEL: 0755 26,786,865 Fax: 0755 26,991,979 welcome insight sample measured, our company can provide technical support. If necessary contact 13510294406 (Li) QQ: 2583343033 QQ: 2,355,368,878 Overview SP5613 is a high-precision off-line switching power supply circuit used in low-power AC / DC charger and adapter. SP5613 primary side sampling accurate constant current, constant voltage control eliminates the need for general application in the optocoupler and TL431. In constant current mode, the output power by the CS pin external sampling resistor Rs settings. In the constant voltage mode, a variety of operating modes of the chip can guarantee higher overall conversion efficiency. In addition, the chip built-in cable drop compensation, thus achieve good load regulation. SP5613 PFM state work in constant current mode, constant voltage mode PWM state light load reduced frequency. SP5613 on soft-start function with a variety of self-healing protection features include cycle-by-cycle current limit protection (OCP), VDD over voltage protection (OVP), VDD over voltage clamp, undervoltage protection (UVLO), over temperature protection. SP5613 has a shaking frequency function can provide better EMI performance. Second, the characteristics? Full voltage range constant voltage accuracy of 5%, 5% constant current accuracy? Using the primary-side feedback control, eliminating an optocoupler and TL431? External constant current value of the output power can be set? Built-in primary side cycle-by-cycle current limit protection (OCP feedback constant current control? built-in adaptive peak current control? built-in primary inductance compensation? can be externally adjusted line drop compensation? electric soft start? built-in leading edge blanking (LEB) function? alternative linear regulator)? undervoltage protection (UVLO), overvoltage protection (OVP), VDD voltage clamp protects four applications? mobile phone charger? PDA, digital camera battery charger? TV, PC auxiliary power? , RCC power |
