TB62757FUG
Step Up Type DC/DC Converter for White LED
The TB62757FUG is a high efficient Step-Up Type DC/DC
Converter specially designed for constant current driving of
White LED.
This IC can drive 2 to 6 white LEDs connected series using a
Li-ion battery.
This IC contains N-ch MOS-FET Transistor for Coil-Switching,
and LED Current (IF) is set with an external resistor.
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.
