The Simple LED Driver Design TCA62735AFLG is a charge pump type DC DC Converter specially
designed for constant current driving of white LED. IC can outputs LED
current 120mA or more to 2.8-4.2V input. IC observes the power-supply
voltage and the output voltage, and does an automatic change to the best
of step up mode 1, 1.5 or 2 times. It is possible to prolong the
battery longevity to its maximum.This IC is especially for driving back
light white LEDs in LCD of PDA, Cellular Phone, or Handy Terminal
Equipment.
This electronic project t LED driver is very simple and require few
external electronic parts. Due of simplicity of this circuit this
project not require additional explanations . If you want to change this
design , please consult the manufactured datasheet.
