TOSHIBA BiCD Digital Integrated Circuit Silicon Monolithic
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.

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..

Application Circuit Example
Protection at the time of LED opening
The zener diode in the application circuit example is necessary for the provision of over-voltage protection for
when the LED becomes open. As the IC does not incorporate a voltage protection circuit, it is strongly advised that
a zener diode be connected.
The zener diode should satisfy the following conditions:
i)
Less than maximum output voltage of 24V
ii) Greater than the total series LED V
F
iii) Less than the maximum output capacitance C
2
.
Moreover, by connecting a protection circuit such as R_ZD in the figure below, it is possible to control the output
current when the LED becomes open, and to use a zener diode of lower tolerance.
An example of IZD control by R_ZD connection. (RSENS = 16 )

) IZD
(mA)
500 0.6
100 1.0
In order to avoid adverse effects on driver characteristics,
Toshiba recommends a resistance of 500 ohms or less.

Dimming using PWM signal input
A dimming function can also by applied using a PWM signal.
[Notes]
When using a PWM signal, the minimum pulse width of the PWM should be greater than 33s.
Duty ratio of PWM function should be set at 10% - 90%.
The recommended PWM frequency should be 100Hz - 10kHz.
