TB62731FU Datasheet (Toshiba) - Step up DC-DC converter

TB62731FU, Step up DC-DC converter

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.
