PRODUCTION DATA
The devices are step up dc/dc converters with true bypass function integrated. They are typically used as preregulators with input voltage ranges from 2.3V to 4.8V, extend the battery run time and overcome input current and input voltage limitations of the system being powered.
While the input voltage higher than boost/bypass threshold, the high-efficient integrated pass-through path connects the battery to the powered system directly.
If the input voltage becomes lower than boost/bypass threshold, the device seamlessly transitions into boost mode operation with a maximum available output current of 3 A.
The following design procedure can be used to select component values for the TPS61281D and TPS61282D (also applicable for TPS61280D/E just by I2C program).
