TB62731FU

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. Weight: 0.016 g (typ.) Features Maximum output voltage: Vo ≤ 28 V Mean LED current values set according to external resistor 14 mA (typ.) @R_sens = 2.7 Ω 20 mA (typ.) @R_sens = 1.8 Ω Supply power: Up to 320 mW supported Compact package: SSOP6-P-0.95B, 6 pins Built-in temperature derating function: LED current derated automatically depend...
