Boost rail from a single cell or 5 V bus
The TPS61096ADSSR is a step-up (boost) converter from Texas Instruments that takes an input from 1.8 V to 5.5 V and delivers an adjustable output up to 28 V. The internal switch is rated for 350 mA, which sets the practical output current ceiling — for a 12 V output from a 3.3 V rail, expect around 80 mA available before the switch current limit is reached.
Output voltage range and setting
Output is adjustable from a minimum of 4.5 V up to 28 V via an external resistor divider. The 28 V ceiling makes this part suitable for biasing LCD backlight strings, driving op-amp rails, or powering sensor modules that need a higher voltage than the input bus.
Junction temperature and package thermal path
Rated for junction temperatures from -40°C to 150°C, the TPS61096ADSSR can operate in hot environments like an engine bay or an enclosed power supply.
