Description



Features:

·TB62734FMG is the high efficient STEP-UP type
·DC/DC converter by which the optimal design was carried out at constant current driver of white LED.
·It is possible to drive 2 ~ 6 white LEDs which connected in series by the lithium ion battery. This IC contains the
·Nch-MOS transistor required for switching of external inductor.
·The forward current of LED is set up by the external resistor. As the brightness control function, an analog voltage input and a pulse input system (PWM) are possible.
·The switching frequency is fixed at around 1.0Mhz.
·This IC is the most suitable as a driver of white LED back
·lighting of the color LCD in the PDA, the cellular phone and the handy terminal machine.
