Frequently Asked Questions
What is the input voltage range of the TPS62203DBVTG4?
The TPS62203DBVTG4 accepts an input voltage range of 2.5V to 6V, with a nominal operating point of 3.6V. This makes it compatible with single-cell lithium-ion batteries (2.7V–4.2V), two-cell alkaline/NiMH packs, and regulated 5V USB rails.
What output voltage and current does the TPS62203DBVTG4 provide?
The TPS62203DBVTG4 provides a fixed 3.3V output with a maximum continuous output current of 300mA (0.3A). It uses voltage-mode pulse-width modulation (PWM) control for stable regulation under varying load conditions.
What switching modes does the TPS62203DBVTG4 support?
The TPS62203DBVTG4 supports both PFM (Pulse Frequency Modulation) and PWM (Pulse Width Modulation) modes. PFM mode is automatically engaged at light loads to minimize quiescent current and extend battery runtime, while PWM mode maintains stable output under heavier loads.
What package does the TPS62203DBVTG4 use and is it RoHS compliant?
The TPS62203DBVTG4 comes in a SOT-23-5 (5-pin SOT-23) surface-mount package, which is extremely compact for space-constrained PCB layouts. It is Pb-free and RoHS compliant, as indicated by the 'G4' suffix in the part number.
