That input floor means it can keep running off a single alkaline or Li-ion cell well into its discharge curve, something a conventional boost that cuts out at 2.5V cannot do. The 500kHz switching frequency keeps the inductor small enough for space-constrained portable gear. ## Output rails and loading Output 1 is a fixed 3.3V rail rated for 1.8A — sized to power a 3.3V MCU plus peripheral loads without a separate post-regulator. Output 2 is a 1.8V LDO at 500mA, typically used for a low-voltage core or I/O bank. The two outputs share the same input, so the total load current drawn from the battery is the sum of both rails divided by the boost efficiency; at 500kHz the switching losses are modest, but the inductor saturation current must cover the peak of the boost stage plus the LDO's draw.","metaTitle":"TPS61107PWG4 Boost + LDO, 0.8V-3.3V Input, 20-TSSOP","metaDescription":"Texas Instruments TPS61107PWG4 dual-output power IC: synchronous boost (3.3V/1.8A) plus LDO (1.8V/500mA).
