Frequently Asked Questions
What is the input and output voltage range supported by TPS84210RKGR?
The TPS84210RKGR accepts an input voltage from 2.95 V to 6 V and can produce an adjustable output voltage starting from 0.8 V, making it compatible with 3.3 V and 5 V power rails and capable of generating sub-1 V core supplies for FPGAs and processors.
How does the integrated module design of TPS84210RKGR reduce PCB area compared to a discrete buck converter?
The TPS84210RKGR integrates the inductor, input/output capacitors, and power MOSFETs in a single 5 mm x 4 mm, 39-pin QFN package, occupying roughly 20 mm² of board area versus 60 mm² or more for an equivalent discrete solution, significantly simplifying layout and reducing component count.
What output current can TPS84210RKGR deliver and how does thermal protection work?
The TPS84210RKGR delivers up to 1 A continuous output current. Built-in thermal shutdown activates at a junction temperature of approximately 150 °C, protecting the device from damage during overload conditions, and the device automatically restarts once the junction temperature drops below the reset threshold.
In which applications is TPS84210RKGR a cost-effective alternative to a multi-chip discrete buck solution?
For designs requiring 1 A at voltages below 5 V in less than 25 mm² of PCB area, such as industrial sensor modules, FPGA auxiliary 1.8 V or 1.2 V rails, and handheld test equipment, TPS84210RKGR eliminates the engineering effort of inductor selection, switching-node layout, and EMC compliance testing that a discrete 2 MHz buck design demands.
