White LED Step-up Converter

The TD8201 is a step-up DC/DC converter designed for driving up to 5 white LEDs in series from a single cell Lithium Ion battery with constant current. Because it directly regulates output current, the TD8201 is ideal for driving  light  emitting  diodes  (LEDs)  whose  light intensity is proportion l  Drives Up to 5 Series White LEDs from 3V\nl  Up to 87% Efficiency\nl  1.25MHz Fixed Switching Frequency\nl  Low 104mV Feedback Voltage\nl  Open Load Shutdown\nl  PWM Dimming\nl  SOT23-6 Packages;
