What is TPS61251DSGT used for?
The TPS61251DSGT is widely used in battery-powered portable devices such as smartphones, wearables, and IoT nodes where a single Li-ion or AAA cell must be boosted to a regulated 3.3V or 5V rail. Its high switching frequency and compact SON package make it ideal for space-constrained LED drivers, white LED backlights, and always-on sensor power supplies. The adjustable output mode and PFM capability also suit low-power standby circuits requiring high efficiency across a broad load range.

Frequently Asked Questions
What is the input voltage range of the TPS61251DSGT?
The TPS61251DSGT operates from an input voltage range of 2.3V to 6.5V, with a nominal input of 3.6V. This wide range makes it compatible with single-cell Li-ion, Li-polymer, and 2-cell alkaline or NiMH battery supplies commonly found in portable electronics.
What output voltage and current can the TPS61251DSGT deliver?
In adjustable mode the TPS61251DSGT can regulate output voltage from 3V up to 6.5V with a peak switch current of 1500mA. The 3.5 MHz switching frequency allows small inductors and capacitors, keeping total solution size extremely compact.
What package does the TPS61251DSGT use and is it RoHS compliant?
The TPS61251DSGT comes in an 8-pin SON (Small Outline No-lead, JEDEC S-PDSO-N8) package measuring approximately 2mm x 2mm, which minimises PCB area. It is fully RoHS and lead-free (Pb-free) compliant, confirmed by its Pbfree Code designation.
What control techniques does the TPS61251DSGT support?
The TPS61251DSGT primarily uses current-mode pulse width modulation (PWM) for precise regulation. It also supports pulse frequency modulation (PFM) control, which reduces switching losses at light loads and significantly improves efficiency in standby or low-power operating conditions.
