It drives up to eight LED strings at 70 mA per channel, using an external MOSFET switch per the step-up topology. PWM dimming input provides the wide contrast ratio needed in monitor, TV, and automotive display backlights. The switching frequency range of 500 kHz to 800 kHz allows the designer to trade inductor size against switching losses. Operating from an 8 V to 30 V supply, it covers standard 12 V and 24 V backlight rails. ## 500–800 kHz switching — inductor and EMI planning The 500 kHz to 800 kHz switching range is a design variable: a lower frequency reduces switching loss but requires a larger inductor; a higher frequency shrinks the magnetics but increases gate-drive loss and may push EMI beyond the CISPR 22 limit without careful layout. Plan the LC filter and snubber around the selected frequency. ## 8 outputs at 70 mA — external switch BOM impact Each of the eight channels requires an external N-channel MOSFET and a current-sense resistor. The controller itself does not contain internal switches — the BOM adds eight FETs, eight sense resistors, and one boost inductor plus output capacitors. Budget board area accordingly.","metaTitle":"TPS61199PWPR DC DC Controller, 8-Channel Boost LED Driver","metaDescription":"Texas Instruments TPS61199PWPR — 8-channel boost LED backlight controller, 500–800 kHz switching, PWM dimming, 8–30 V supply, 70 mA/ch, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Type":"DC DC Controller","Series":"-","Dimming":"PWM","Package":"Tape & Reel (TR); Cut Tape (CT)","Topology":"Step-Up (Boost)","Frequency":"500kHz ~ 800kHz","Applications":"Backlight","Mounting Type":"Surface Mount","Package / Case":"20-PowerTSSOP (0.173\\\", 4.40mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Output":"-","Number of Outputs":"8","Internal Switch(s)":"No","Base Product Number":"TPS61199","Operating Temperature":"-40°C~85°C(TA)","Voltage - Supply (Max)":"30V","Voltage - Supply (Min)":"8V","Supplier Device Package":"20-HTSSOP","Current - Output / Channel":"70mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/95c8da0fc07d5fbc4d401f15659ba8b4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61199PWPR/alternatives.json"},"ai":{"faq":[{"question":"Does TPS61199PWPR need an external MOSFET?","answer":"Yes.
