現(xiàn)品表示 ；
TB62750FTG is the high efficient STEP-UP type DC/DC converter by
which the optimal design was carried out at constant current driver of
white LED.
It is possible to drive white LEDs whose constant output current is 800mA
by the lithium ion battery.
This IC contains the Nch-MOS transistor required for switching of external
inductor.
The forward current of LED is set up by the external resistor.
This IC is the most suitable as a driver of camera flashes and strobes in
the cellular phone, the PDA, the DSC, and other mobiles.
