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 Supply of high precision primary side feedback switching power supply chip SP5618, SP5616, SP5615, SP5619, SP5613, SP5610 is a high-precision off-line switching power supply circuit for low power AC / DC charger and adapter. SP5618 primary side sampling precision 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. SP5618 PFM state work in constant current mode, constant voltage mode PWM state, reduced frequency at light loads. SP5618 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. SP5618 has a shaking frequency function, can provide better EMI performance. Characteristics of full voltage range of 5% constant voltage accuracy, precision constant current of 5% using the original side feedback control, eliminates the optocoupler and TL431 external built-in original PSR constant current control built-in constant current value of the output power can be set adaptive peak current control built-in primary inductance compensation can be externally adjusted line voltage drop compensation on soft-start built-in leading edge blanking (LEB) cycle-by-cycle current limit provides protection (OCP), under voltage protection (UVLO), overvoltage protection ( OVP), the VDD voltage clamp protection |
