Dual-output PMIC for mixed-voltage rails
The Texas Instruments TPS61107RGER integrates a synchronous step-up (boost) converter and a linear LDO in a single 24-VQFN package. The boost delivers 3.3V at 1.8A from an input as low as 0.8V; the LDO provides a clean 1.8V rail at 500mA. Switching frequency is fixed at 500kHz.
Input range and output sequencing
Input voltage range spans 0.8V to 3.3V, suiting single-cell alkaline, NiMH, or Li-primary battery applications. The two outputs are independent — no internal sequencer — so the designer controls power-up order via external enable pins or the LDO input rail.
Housed in a 24-VFQFN with exposed pad (4x4 mm body). Surface-mount assembly; the small footprint suits space-constrained portable designs.
