Frequently Asked Questions
What input voltage range does the TPS62046DRCR support and what switching modes are available?
The TPS62046DRCR operates over an input range of 2.5V to 6V and supports both voltage-mode PWM for heavy loads and PFM mode for light-load conditions, ensuring high efficiency across the entire operating range of lithium-ion and alkaline battery-powered systems.
How does PFM mode on the TPS62046DRCR extend battery life in IoT or wearable applications?
In PFM mode the TPS62046DRCR reduces switching frequency when load current falls, dramatically lowering quiescent current consumption and allowing battery-operated IoT sensor nodes and wearable devices running from a 3.7V lithium cell to remain operational for significantly longer periods between recharges.
What package does the TPS62046DRCR use and how does it compare to larger regulator packages for PCB layout?
The TPS62046DRCR uses a 10-pin SON (S-PDSO-N10) package with exposed thermal pad, offering a significantly smaller PCB footprint than SOT-23 or SOIC options while providing good thermal dissipation for the step-down switching regulator operating up to 6V input.
For a 3.3V output rail design, what is the minimum input voltage the TPS62046DRCR can sustain regulation from?
The TPS62046DRCR supports a minimum input voltage of 2.5V and can maintain a regulated 3.3V output as long as the input exceeds the output by the required headroom, making it suitable for end-of-life lithium battery scenarios and multi-cell alkaline systems where input drops near 3.3V.
