Active production — no end-of-life concern for this BOM line
The TPS610985DSER: ROHS3 compliant, so it clears EU/UKCA restricted-substance requirements without an exemption. No date-code restrictions beyond standard TI supply.
Dual-output architecture — one boost, one LDO, both 3V
The TPS610985DSER integrates a synchronous boost converter and a linear (LDO) regulator in a single 6-WSON package. Output 1 delivers 3V at 350mA from the boost stage; output 2 delivers 3V at 200mA from the LDO. Input supply range spans 0.7V to 4.5V — the boost starts from a single-cell alkaline at end-of-life (0.9V) and runs through a Li-ion cell at full charge (4.2V). The LDO post-regulates the boost output, so the second rail inherits the boost's ripple rejection. Operating temperature covers -40°C to 85°C, which suits outdoor IoT gateways, portable medical gear, and industrial sensor nodes that see seasonal extremes.
Package and board-fit — 1.5x1.5mm WSON
Housed in a 6-pin WFDFN (6-WSON) with a 1.5x1.5mm body — the supplier device package is 6-WSON (1.5x1.5). The small footprint suits space-constrained PCBs in wearables, hearables, and compact sensor modules. No sequencer, LED driver, or supervisor on-chip — the two outputs power up in the boost-first order inherent to the topology.
