APPLICATIONS White LED Backlighting when combined with SP7615 or SP7616 Large LED arrays for general lighting General boost, flyback, or SEPIC converters GENERAL DESCRIPTION
The SP7606 is a fixed frequency boost controller designed to drive loads up to 38V output
voltage. 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.
