Its input range spans 1.8V to 5.5V, meaning it can operate from a Li-ion cell down to its end-of-discharge voltage of roughly 2.7V and still hold the output steady, while also handling a 5V USB bus input without issue. ## 3.6A switch current — sizing the output load The internal switch is rated for 3.6A, which translates to a practical continuous output current of roughly 2A at 3.3V from a 3.6V input, before hitting the switch current limit or thermal constraints in the 16-HTSSOP package. The switching frequency is fixed at 600kHz, a common choice that balances inductor size against switching losses — a 4.7 µH to 10 µH inductor typically works for most 3.3V output designs at this frequency.","metaTitle":"Texas Instruments TPS61031PWPRG4 Boost Converter","metaDescription":"Texas Instruments TPS61031PWPRG4 step-up DC-DC converter.

The 1.8V minimum input voltage allows operation from a single Li-ion cell down to its discharge floor, and the synchronous rectifier improves efficiency at light loads, which directly extends battery run time in portable designs."},{"question":"Can TPS61031PWPRG4 replace TPS61031PWPR?","answer":"Yes, the TPS61031PWPRG4 is the Tape & Reel packaged variant of the same base device TPS61031. The PWPRG4 suffix indicates the reel format; the PWPR suffix typically refers to tube or alternative packaging. Electrically they are identical, so the PWPRG4 is a drop-in replacement for the PWPR in a reel-fed assembly line."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS61031PWPRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS61031PWPRG4 when reusing this data.
