It accepts a nominal 8.6 V to 14.7 V input rail — typically a regulated 12 V bus from the main power supply — and generates the multiple regulated voltages needed by the source driver, gate driver, and timing controller. ## Supply rail and thermal layout for the 48-VQFN The 48-VFQFN with exposed pad (6x6 mm body) requires a thermal land pattern on the PCB with multiple vias to an internal ground plane. The supply range (8.6 V to 14.7 V) means the part runs directly off a 12 V bus without a pre-regulator, but the input capacitor ESR and ripple current rating must be sized for the peak load step.","metaTitle":"TI TPS65178RSLR LCD Bias IC, 8.6V-14.7V Input, 48-VQFN","metaDescription":"Texas Instruments TPS65178RSLR LCD TV/Monitor bias supply IC. 8.6V~14.7V input, -40°C~85°C, 48-VFQFN exposed pad.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Applications":"LCD TV/Monitor","Mounting Type":"Surface Mount","Package / Case":"48-VFQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Supply":"-","Voltage - Supply":"8.6V ~ 14.7V","Base Product Number":"TPS65178","Operating Temperature":"-40°C~85°C","Supplier Device Package":"48-VQFN (6x6)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/02498db4a1d351f45e63afb9a9bb2db1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS65178RSLR/alternatives.json"},"ai":{"faq":[{"question":"Is TPS65178RSLR a direct replacement for the base TPS65178?","answer":"The TPS65178RSLR shares the same base product number (TPS65178) and the same 48-VFQFN package. The RSLR suffix indicates Tape & Reel packaging. Functionally it is the same die in the same package; the reel suffix is a logistics variant, not a design change.
