Frequently Asked Questions
What is the input voltage range of the TPS61085PWR?
The TPS61085PWR operates over an input voltage range of 2.5V to 6V, making it compatible with single-cell Li-ion/Li-polymer batteries (2.7V–4.2V) as well as 3.3V and 5V regulated supply rails commonly found in embedded systems.
What output voltage can the TPS61085PWR achieve?
The TPS61085PWR supports an adjustable output voltage from approximately 3V up to 14V, set by an external resistor voltage divider connected to the feedback pin. This flexibility allows designers to target common rails such as 5V, 9V, 12V, or custom voltages for LED drivers and display bias circuits.
What is the switching frequency of the TPS61085PWR and how does it affect design?
The TPS61085PWR uses a fixed switching frequency of 1.2MHz. This high frequency allows the use of smaller external inductors and capacitors, reducing overall PCB area. It also pushes switching noise above the AM radio band, simplifying EMI filtering in noise-sensitive applications.
What package does the TPS61085PWR come in and what are the thermal considerations?
The TPS61085PWR comes in a 14-pin HTSSOP (PWP) package with an exposed PowerPAD on the bottom. The PowerPAD must be soldered to a ground copper pour on the PCB to achieve the rated thermal performance. This package enables the device to handle the heat generated at high output currents without requiring a heatsink.
Where can I buy the TPS61085PWR and what is the price?
