TB62758FTGO,EL
TB62758FTG TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB62758FTG Step up type DC/DC converter built in 6 ch sync driver for White LED TB62758FTG is a high efficient step-up type DC/DC controller specially designed for constant current drive of white LED. This IC can drive white LEDs with constant current by dividing white LEDs, which are serial connected with lots of LEDs, into 6 lines. LED current (IF) is set with an external resistor and dimming control is available by PWM signal. This IC is especially for driving back light white LEDs in large LCD which is 10 inches or more. Characteristics Weight :0.021g (TYP) • Variable LED current (IF) is 20mA @RISET = 11kΩ • IC package:VQON24 • Input Voltage range : 7.5V to 22V • Switching frequency:200kHz to 1.5 MHz • Set by the resistance connected to fSET terminal Constant current driver Built in open detection • Built in short-circuit detection Built in thermal shutdown circuit 150℃(MIN) • Built in output over voltage protecting circuit:42V(MIN) • Built in output reduced voltage protection • Built in input over current protection • Built in SW terminal protection 6.8V to 22V(VOUT<38V,IF:20mA) 1 2010-4-26
