Frequently Asked Questions
What is the input voltage range and maximum output current of the TPS62224DDCTG4?
The TPS62224DDCTG4 accepts an input voltage from 2.5 V to 6 V and delivers up to 400 mA output current, making it well suited for Li-ion single-cell battery applications where input voltage drops from 4.2 V fully charged to approximately 2.7 V at end of discharge.
How does the PFM mode in the TPS62224DDCTG4 improve efficiency for battery-powered IoT designs?
In PFM (pulse-frequency modulation) mode, the TPS62224DDCTG4 reduces switching activity at light loads, lowering quiescent current to microamps and significantly extending battery life in IoT sensor nodes and wearables that spend most of their time in standby below 50 mA load.
How compact is the TPS62224DDCTG4 solution footprint compared to larger LDO regulators?
The TPS62224DDCTG4 is housed in a 5-pin SOT-23 package measuring approximately 1.6 mm × 1.6 mm, and the full switching regulator solution requires only an inductor and two capacitors, achieving a smaller total footprint than many 8-pin LDO regulators with equivalent current rating.
Which fixed output voltage versions are available and how does that affect design selection?
The TPS62224 family offers fixed output voltage variants for 1.8 V, 2.5 V, and 3.3 V, allowing engineers to select a specific MPN matched to their target rail without needing an external feedback resistor divider, reducing BOM complexity and improving output accuracy.
