60V Buck LED Driver DESCRIPTION APPLICATIONS SC61002 is the monolithic IC designed for a DC/DC LED driver applications step-down LED driver capable of driving Backlighting for flat panel displays 1.5A/3A load without an additional transistor. General purpose constant current source The input voltage range is up to 60V. Its Automotive feedback voltage, VFB, is 200mV. The SC61002 Chargers 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. SC61002 is available in standard TO-263 and SOP-8 with power pad . package.
