恒压IC、恒压方案、恒压恒流方案 SL3016
详细信息 DEscriptION SL3016 is th e monolithic IC designed for step-down LED driver capable of driving 1.6A-3.5A load without additional transistor. The input voltage range is up to 60V. Its feedback voltage,VFB,is 200mV. Thechip operates at a switching frequency of 52kHz. The external shutdown function is controlled by a logic level on the ON/OFF pin and then the circuit comes into the standby mode with ISTBY~50μA (typ.). The ON/OFF pin may be used for the analog dimming. As the voltage on the ON/OFF pin is increased from 0.07V to 0.67V, the voltage on the FB pin falls from 200mV to 0. The self-protection features include a cycle-by-cycle current limit and a thermal protection.SL3016is available in standard TO-263,TO252and SOP-8 with power pad package.
