Frequently Asked Questions
What is the input voltage range of TPS62040DGQ?
The TPS62040DGQ operates from a 2.5V to 6V input voltage range, with a nominal input of 3.6V. This makes it compatible with single-cell Li-ion batteries (2.7V–4.2V) as well as standard 3.3V and 5V system rails.
What output voltage can TPS62040DGQ deliver and what is its maximum output current?
TPS62040DGQ provides an adjustable output voltage from 0.7V to 6V, set by an external resistor divider. It delivers up to 1.2A continuous output current, making it suitable for powering microcontrollers, DSPs, and other medium-load digital circuits.
What is the switching frequency of TPS62040DGQ and why does it matter?
The TPS62040DGQ switches at a fixed 1250kHz frequency. This high frequency allows the use of smaller external inductors and capacitors, reducing overall solution size and cost — ideal for space-constrained portable and wearable designs.
Does TPS62040DGQ support light-load efficiency optimization?
Yes. In addition to its default PWM (Pulse Width Modulation) voltage-mode control, TPS62040DGQ also supports PFM (Pulse Frequency Modulation) mode. At light loads, the device automatically transitions to PFM to maintain high efficiency and reduce quiescent current.
What package does TPS62040DGQ use and where can I buy it?
TPS62040DGQ is housed in a 10-pin HTSSOP EP (Small Outline Package with exposed pad), which provides excellent thermal performance in a compact footprint. It is available from authorized distributors worldwide starting from approximately $0.48 per unit, with stock available for immediate shipping.
