Frequently Asked Questions
What is the input voltage range of the TPS61252DSGT?
The TPS61252DSGT operates from an input voltage range of 2.3V minimum to 6V maximum, with a nominal input of 3.6V. This makes it ideal for single-cell Li-ion batteries (2.5V–4.2V) and multi-cell alkaline or NiMH battery stacks.
What output current can the TPS61252DSGT deliver?
The TPS61252DSGT can deliver up to 1500mA (1.5A) of adjustable output current. The device supports both fixed output and a fully adjustable mode operating from 3V to 6.5V output, giving designers flexibility for a wide range of load requirements.
What package does the TPS61252DSGT come in?
The TPS61252DSGT is housed in an 8-pin SON (Small Outline No-lead) package, also known as DSG package, with a compact 3mm x 3mm footprint. This leadless package offers excellent thermal performance and is suitable for space-constrained PCB designs.
What are the typical applications for the TPS61252DSGT?
The TPS61252DSGT is commonly used in portable electronics including smartphones, tablets, wearables, IoT devices, handheld medical instruments, and battery-powered sensor nodes. Its wide input range and high efficiency make it especially valuable for battery boost applications requiring stable 3.3V or 5V output rails.
What control modes does the TPS61252DSGT support?
The TPS61252DSGT uses current-mode pulse width modulation (PWM) as its primary control technique, which provides fast transient response and excellent loop stability. It also supports pulse frequency modulation (PFM) for improved efficiency at light loads, reducing quiescent current consumption in battery-powered applications.
