Overview
TOSHIBA BiCD Digital Integrated Circuit Silicon Monolithic TB62731FU TB62731FU Step-up DC-DC Converter for White LED Driver The TB62731FU is an LED driver which uses a high power efficiency step-up DC-DC converter.
The converter turns on/off from 2 to 6 white LEDs in series.
The IC incorporates an N-channel MOSFET transistor which switches a coil.
Also, a function which reduces LED current depending on increase in temperature.
The mean LED current can be easily set using an external resistor.
The IC is ideal as a driver for LED light sources used as liquid crystal backlights for PDAs, cellular phones, and handy terminals.
