Boost plus LDO on one die
The TPS61107PWR from Texas Instruments packs a synchronous boost converter and a linear (LDO) regulator into a single 20-TSSOP package, generating two regulated output rails from a low-voltage battery input. Output 1 delivers 3.3V at 1.8A from the boost stage; Output 2 provides 1.8V at 500mA from the LDO, a common split for powering a 3.3V logic rail and a 1.8V core or I/O supply in portable devices.
500 kHz switching, industrial temperature range
Switching at 500kHz, the boost converter uses small external inductors and capacitors, saving board area in space-constrained designs. The 20-TSSOP package (0.65mm pitch) is a standard fine-pitch SMD footprint; layout engineers should note it is a leaded package, not a QFN, so thermal dissipation relies on the PCB copper rather than an exposed pad.
No official successor or replacement part number is listed on the TI lifecycle record for this exact order code.
