It integrates the switching FET internally, so the BOM stays tight — just the inductor, input/output caps, and the LED itself. The 500 mA flash output is rated for the pulse current needed to drive a high-brightness LED during capture. ## PWM dimming and supply range Dimming is handled via PWM, which is the standard interface for camera flash controllers and application processors. Output voltage is regulated to 5.5 V maximum, which is the typical forward voltage ceiling for a series-connected flash LED. The single-output topology means one LED per driver — if the design needs multiple LEDs, each gets its own TPS61055. ## Package and temperature — field-fit check It comes in a 12-pin DSBGA (12-DSBGA) package — that is a 0.4 mm pitch wafer-level chip-scale package. No lab bench needed for rework if you have a hot-air station with a fine nozzle, but the tiny bumps mean the board must have a soldermask-defined pad pattern.","metaTitle":"TPS61055YZGR DC DC Regulator, 2 MHz Boost, 500 mA Flash","metaDescription":"TI TPS61055YZGR DC DC regulator, step-up boost topology, 2 MHz switching, 500 mA flash output, PWM dimming, 12-DSBGA, 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 Regulator","Series":"-","Dimming":"PWM","Package":"Tape & Reel (TR) Cut Tape (CT)","Topology":"Step-Up (Boost)","Frequency":"2MHz","Applications":"Camera Flash, Lighting","Mounting Type":"Surface Mount","Package / Case":"12-UFBGA, DSBGA","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Output":"5.5V","Number of Outputs":"1","Internal Switch(s)":"Yes","Base Product Number":"TPS61055","Operating Temperature":"-40°C ~ 85°C (TA)","Voltage - Supply (Max)":"6V","Voltage - Supply (Min)":"2.5V","Supplier Device Package":"12-DSBGA","Current - Output / Channel":"500mA (Flash)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4977","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e760f957ab06e4daee7afc3b022b9190.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61055YZGR/alternatives.json"},"ai":{"faq":[{"question":"What is the typical application for TPS61055YZGR?","answer":"It is designed for camera flash and general lighting applications.
