The SP7606 was developed to be used in conjunction with the SP7616 to drive a wide range of led chains that require high anode voltages. The ability to disconnect the output voltage feedback resistors (DD Pin) reduces shutdown current. The high switching frequency allows the use of tiny external components and saves layout space and cost. The SP7606 is available in a space-saving 8-pin 2x3 DFN.
