TB62733FTG
Charge Pump type DC/DC Converter for White LED Driver
Application
Charge Pump type DC/DC Converter / White LED Driver
Features
TB62733FTG is charge pump type DC to DC Converter that is accept from
2.8 up to 4.2V input and continue to up converting operation until FB terminal
is equal to 0.4V. (1.5 times up converting)
This device provides over 190mA at Vin=3.9V as the maximum current, and
two outputs structure may help to design the backlighting system such as
the system having two displays that are main and sub LCD displays.
Also, this is used for the power supply of flash lighting by using two outputs
At the same time.
