The frequency also places the fundamental ripple above the audio band, so the inductor does not whine audibly during torch operation. ## Package and layout — 20-bump DSBGA The small footprint — roughly 1.6 mm × 2.0 mm — saves board area but demands careful decoupling placement; the input and output capacitors should sit within 2 mm of their respective bumps to keep switching loops tight.","metaTitle":"TI TPS61301YFFR DC-DC Boost Regulator, I²C Dimming","metaDescription":"Texas Instruments TPS61301YFFR: step-up boost regulator for camera flash, 2.5V-5.5V input, 5.7V output, 3 channels at 400/800 mA, I²C dimming, 20-DSBGA, -40 to","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":"I²C","Package":"Tape & Reel (TR)","Topology":"Step-Up (Boost)","Frequency":"1.92MHz","Applications":"Camera Flash","Mounting Type":"Surface Mount","Package / Case":"20-UFBGA, DSBGA","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Output":"5.7V","Number of Outputs":"3","Internal Switch(s)":"Yes","Base Product Number":"TPS61301","Operating Temperature":"-40°C~85°C(TA)","Voltage - Supply (Max)":"5.5V","Voltage - Supply (Min)":"2.5V","Supplier Device Package":"20-DSBGA","Current - Output / Channel":"400mA, 800mA (Flash)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2750","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/82fa953d0f98bb165443c78cfa8df307.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61301YFFR/alternatives.json"},"ai":{"faq":[{"question":"Does TPS61301YFFR support I²C dimming?","answer":"Yes, the TPS61301YFFR uses an I²C interface for dimming control, allowing the host to set torch current, flash current, and timing registers without additional PWM lines."},{"question":"What is the output current capability of TPS61301YFFR?","answer":"Each of the three outputs delivers 400 mA in torch mode and 800 mA in flash mode.
