Key Features
- Switched-capacitor charge pump with 0.9 V minimum start-up input enabling operation directly from a single alkaline or NiMH cell
- Regulated 3 V output from 0.9–1.8 V input range, also operable at 3 V input, providing flexible supply compatibility
- Ultra-compact 10-pin MSOP footprint (JESD-30 S-PDSO-G10) with Pb-free RoHS compliance for miniaturized portable product designs
Applications
The TPS60311DGSG4 is designed for single-cell battery-powered devices such as wireless sensors, hearing aids, and remote controls where the supply voltage can drop below 1 V during discharge. Its charge pump architecture eliminates the need for inductors, simplifying PCB layout and reducing EMI in noise-sensitive portable medical and consumer electronics. The ability to operate directly at 3 V also allows flexible integration into mixed-voltage supply trees.

Frequently Asked Questions
What is the input voltage range of the TPS60311DGSG4?
The TPS60311DGSG4 operates with an input voltage from 0.9 V minimum to 1.8 V maximum, with a nominal input of 1 V. It can also operate directly from a 3 V supply, making it versatile for single-cell alkaline, NiMH, and lithium coin cell battery applications.
What type of converter is the TPS60311DGSG4 and does it need inductors?
The TPS60311DGSG4 is a switched-capacitor charge pump regulator, which means it uses only external capacitors — no inductors are required. This simplifies board layout, reduces cost, and minimizes electromagnetic interference compared to inductor-based DC-DC converters.
What package does the TPS60311DGSG4 come in?
The TPS60311DGSG4 is housed in a 10-pin MSOP package (JESD-30 code S-PDSO-G10). It is Pb-free and RoHS compliant per JESD-609 code e4, suitable for compact, lead-free PCB assemblies in portable consumer and medical devices.
What is the output voltage of the TPS60311DGSG4?
The TPS60311DGSG4 provides a regulated 3 V output voltage. It boosts the input from the 0.9–1.8 V range up to 3 V, and can also pass through a 3 V input directly, making it suitable for powering microcontrollers and RF modules that require a stable 3 V rail.
