SP7616 is the 4-channel constant-current linear white LED driver with operating voltage in 4.5 ~ 30V, and each channel supports the maximum of ω irregular current. SP7616 contains current-matching circuit, which allows the current difference between each channel to be less than 1.5%. SP7616/SP7615's typical application circuit is shown in Figure 1, each channel of SP7616 supports 60mA current and SP7615 supports 126mA current. In the SP7616 typical application circuit shown in Figure (a), if DIN (N × UF + UDROP), then the current flowing through the 4-channel white LED is constant and matched.
