SP2260

SP2260 60V Buck LED Driver DESCRIPTION SP2260 is the monolithic IC designed for a step-down LED driver capable of driving 1.5A/3A load without an additional transistor. The input voltage range is up to 60V. Its feedback voltage, VFB, is 200mV. The SP2260 operates at a switching frequency of 52kHz. The external shutdown function is controlled by a logic level on the EN pin and then the circuit comes into the standby mode with ISTBY~50µA (typ.). As the voltage on the EN 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. SP2260 is available in standard TO-263 and SOP-8 with power pad. package.
