What are the key features of TPS826721SIPT?
- 600mA output current with 2.3V to 4.8V input range for single-cell Li-ion battery applications
- Automatic PFM/PWM mode switching maximizes efficiency at light loads for extended battery life
- Fully integrated design in tiny 8-ball BGA package minimizes external component count
What is TPS826721SIPT used for?
The TPS826721SIPT is designed for portable consumer electronics such as smartphones, wearables, and IoT sensors where board space is limited and battery life is critical. Its 600mA output capability and automatic PFM control enable efficient power conversion from single-cell Li-ion batteries operating down to 2.3V. The low-noise PWM operation makes it suitable for RF-adjacent subsystems and precision analog circuits where switching noise must be minimized.

Frequently Asked Questions
What is the input voltage range of the TPS826721SIPT and which battery chemistries does it support?
The TPS826721SIPT operates from a 2.3V minimum to 4.8V maximum input voltage, covering the full discharge curve of single-cell Li-ion and Li-polymer batteries. With a nominal input of 3.6V it can operate through most of the usable battery capacity, delivering up to 600mA regulated output current without dropout even at low state of charge.
How does PFM mode improve efficiency in a wearable device running the TPS826721SIPT at light loads?
In PFM (pulse frequency modulation) mode, the TPS826721SIPT skips switching cycles when load current is low, drastically reducing switching losses. At currents well below the 600mA rated output, this can improve efficiency by 10% to 20% versus fixed-frequency PWM operation, directly extending battery runtime in wearable and IoT devices where the processor idles most of the time.
What package does the TPS826721SIPT use and how does it compare to standard SOT-23 regulators in terms of PCB footprint?
The TPS826721SIPT comes in an 8-ball BGA (PBGA-B8) package with a very small footprint, significantly smaller than an equivalent SOT-23-5 or SOT-23-6 package. The BGA format reduces the land area to approximately 1.5 mm x 1.5 mm, making it about 50% smaller than a typical SOT-23 regulator of similar output current rating, which benefits ultra-compact wearable PCB layouts.
When should a designer choose TPS826721SIPT over a linear LDO regulator for a 3.3V to 1.8V conversion at 500mA?
A linear LDO converting 3.3V to 1.8V at 500mA dissipates 750mW as heat (1.5V drop × 500mA), which may require thermal management. The TPS826721SIPT's switching topology achieves efficiencies above 85%, reducing dissipation to under 130mW at the same operating point, improving thermal performance and extending battery life in compact enclosures where heat dissipation is constrained.
