TB62736FUG
Step-up Type DC-DC Converter for White LEDs
The TB62736FUG is a high efficiency step-up type DC/DC
converter that is designed especially for use as a constant current
driver of white LEDs.
It is possible to drive 2 - 6 white LEDs connected in series using a
lithium-ion battery. (Typ. 4 White LEDs)
This IC incorporates an N-ch-MOS transistor required for
switching of an external inductor.
The forward current of the LEDs can be controlled by an external
resistor. An analog voltage input and a pulse input system (PWM)
can be used as a brightness control function.
The switching frequency is fixed at around 1.1 MHz.
This IC is best suited for use as a driver of white LED back
lighting in color LCDs in PDAs, cellular phones and handy
terminal devices.

Pin Assignment (top view)
Note 1:
The IC may break if mounted 180 degrees in reverse. Ensure the device is correctly orientated before
assembley
.
Note 2: The control pin must be set to a certain logic level, as unstable output could result if the pin is left open..
Note 3: Regarding soldering, the following conditions were confirmed
(1) Use of Sn-63Pd solder bath
