FEATURE
The TB62732FU is a LED driver by the high efficiency
step up type DC-DC converter that 2-4 serial white LED
can be turned on.
This IC builds in the NchMOS FET transistor to switch
the coil, and builds in the function which derate
the LED current corresponding to the rise in temperature.
And, the average LED current can be set up easily
by the resistance with the outside.
This IC is the most suitable as a driver
of the LED liquid crysta back light of the PDA,
the cellular phone and the the handy terminal.
CHARACTERISTICS
*Maximum output voltage Vo =< 17V
*The variable setup of the average LED current value by
the resistance with the outside.
18 mA (typ) @ R_sens = 2.7 ohms
20 mA (typ) @ R_sens = 2.4 ohms
*Supply electric power
It is turned on to the 320 mW load.
*Compact package
SSOP6 - P - 0.95B ( SOT23-6pin )
*The LED current derating function is built in.
The derating of LED current vs set temperature,
on the automatic operation.
*High efficiency
80% of the efficiency. @ 2-3LEDs turn on. IF=20mA (typ) )
Ron=2.0 ohms (standard) @ Vin = 3.0 - 5.5V
The power MOS transistor building in of low Ron.
*Pin assignment (Top View)
Note 1:
Be careful of handling because there is a terminal which is poor at ESD in this product.
