The part integrates the power switch, compensation, and fault protection in a 20-WFQFN exposed pad package measuring 3x3 mm. ## Input range and output selection — fit for the BOM The 4.5V to 16V input covers the typical 12V or 5V intermediate rails found in satellite receiver boards, with headroom for ripple. The 13.4V and 18.2V outputs match the standard LNB supply levels per EN 50494; the single output pin switches between them, so the BOM needs only one inductor and one output capacitor. ## Package and thermal — the exposed pad is not optional Without it the junction temperature rises above the 85°C ambient ceiling at full load. The pad is also the ground return for the power stage — layout inductance between pad and input cap directly affects switching noise.","metaTitle":"TI TPS65235RUKR DC-DC Converter, 4.5V-16V Input","metaDescription":"Texas Instruments TPS65235RUKR DC-DC converter for satellite set-top box designs.
