The boost channel delivers a regulated 3.3 V at up to 1.8 A, while the LDO provides an adjustable output from 0.9 V to 3.6 V at 500 mA — enough to power a mixed-voltage system from a single low-voltage battery or 3.3 V rail. The 500 kHz switching frequency is a middle ground — fast enough to keep inductor size small, slow enough to avoid tight layout constraints on a 2-layer board. Housed in a 20-TSSOP with 0.65 mm pitch and a 4.40 mm body width, the part reflows on a standard lead-free profile. The moisture sensitivity level is not stated in this listing, so a bake before reflow is prudent if the tube seal has been compromised — a precaution that avoids the popcorning that can lift the thin TSSOP leads.","metaTitle":"TPS61103PWG4 Dual-Output Power IC, Boost + LDO, 20-TSSOP","metaDescription":"TI TPS61103PWG4 dual-output power IC: synchronous boost (3.3V/1.8A) plus LDO (0.9-3.6V/500mA).
