PWM dimming input allows direct brightness control from a microcontroller or PWM source, eliminating the need for an external DAC or analog dimming circuit. ## 1.2 MHz switching frequency and inductor selection The 1.2 MHz switching frequency keeps the inductor small and pushes switching noise above the audible band.","metaTitle":"TPS61169DCKR LED Backlight Driver, Boost, 1.2 MHz, SC-70-5","metaDescription":"Texas Instruments TPS61169DCKR DC-DC boost regulator for LED backlight, 1.8 A switch, PWM dimming, -40°C to 125°C, SC-70-5.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Mfr":"Texas Instruments","Type":"DC DC Regulator","Series":"-","Dimming":"PWM","Package":"Tape & Reel (TR); Cut Tape (CT)","Topology":"Step-Up (Boost)","Frequency":"1.2MHz","Applications":"Backlight","Mounting Type":"Surface Mount","Package / Case":"5-TSSOP, SC-70-5, SOT-353","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Output":"-","Number of Outputs":"1","Internal Switch(s)":"Yes","Base Product Number":"TPS61169","Operating Temperature":"-40°C~125°C(TJ)","Voltage - Supply (Max)":"5.5V","Voltage - Supply (Min)":"2.7V","Supplier Device Package":"SC-70-5","Current - Output / Channel":"1.8A (Switch)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0000","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61169DCKR/alternatives.json"},"ai":{"faq":[{"question":"What is the switching frequency of TPS61169?","answer":"The switching frequency is 1.2 MHz.
