DESCRIPTION
The TP3984 is a constant current step-up converter specifically designed to drive white LEDs. The Step-up converter  topology  allows  series  connection  of  the white LEDs so the LED currents are identical for uniform brightness. The TP3984 switches at 1.1MHz, allowing  the  use  of  tiny  external  components. The input and output capacitor can be as small as 1µF, saving space and cost versus alternative solutions. A low 0.25V feedback voltage minimizes power loss in the   current   setting   resistor   for   better   efficiency. TP3984  is enhanced with Soft-Start function and that could significantly reduce  noise induced by capacitor.
The TP3984 is available in low profile SOT23-6 package.
