Description
The YB1508 is a step-up DC-DC converter that acts as a current source to drive up to 8 white LEDs in series. It provides uniform brightness by ensuring identical LED currents without the need for ballast resistors. The light intensity of the LEDs is directly proportional to the current passing through them. The YB1508 also offers output over voltage protection to prevent device damage in case of faulty LED or open circuit conditions. It features one-pin shutdown and multiple methods of dimming control.
