TCA62735AFLG
Charge Pump type DC/DC Converter for White LED Driver
The TCA62735AFLG is a charge pump type DC/DC Converter
specially designed for constant current driving of White LED.
This IC can outputs LED current 120mA or more to 2.8-4.2V input.
This 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 device is Pb-free product.
