The 2.3V minimum input lets this part run from a nearly depleted Li-ion cell. The 6V maximum input means it is not intended for 12V or higher intermediate rails.
The TPS61085 lets you select between 650 kHz and 1.2 MHz via a logic pin.
If you are qualifying this into a production BOM, the active status means there is no LTB risk in the near term, and the standard MSOP-8 footprint gives you flexibility for second-sourcing if needed.
Yes, it is ROHS3 compliant per the Texas Instruments lifecycle record.
The LM2750LD-ADJ/NOPB is a step-up charge pump from TI, but it is a different topology (charge pump vs inductor-based boost), delivers only 120 mA output, and operates at 1.7 MHz fixed frequency. It is not a pin-compatible or drop-in alternative — the TPS61085 is in a different class for higher-current boost applications. For a true functional equivalent, look at other TI boost converters with a 2A switch and adjustable output, such as the TPS61087 or TPS61089 series, but verify pinout and compensation separately.
