The 1.2 A flash current is the peak rating for the flash event — the part is sized to dump that current into the LED for the typical 100–300 ms flash pulse. ## PWM dimming and input voltage — design-in checks Dimming is controlled via a PWM input, which lets the camera processor set the flash intensity by varying the duty cycle. The PWM signal directly modulates the boost converter's output current, so the timing of the PWM pulse relative to the camera shutter is critical — the datasheet's application section covers the recommended PWM frequency and minimum pulse width. The input voltage range of 2.5 V to 6 V covers a single-cell Li-ion battery (nominal 3.6 V, full charge 4.2 V) and a 2-cell alkaline pack. At the low end, the boost converter maintains regulation down to 2.5 V, which means the flash can fire even when the battery is nearly depleted — a common requirement in portable cameras. ## 12-DSBGA package — reflow and inspection notes The TPS61050AYZGT comes in a 12-bump DSBGA package (0.4 mm pitch, wafer-level chip-scale). This package demands a tight stencil aperture for solder paste deposition and a reflow profile that matches the JEDEC standard for lead-free assembly. Post-reflow inspection requires X-ray or side-view microscopy to confirm solder bump wetting on all 12 bumps. A head-in-pillow defect on a single bump can cause intermittent flash failure that is hard to catch in functional test. The base product number TPS610 covers a family of flash drivers; the AYZGT suffix specifies the 12-DSBGA package and the tape-and-reel shipping format.","metaTitle":"TPS61050AYZGT DC-DC Boost Regulator, 1.2 A Flash, 12-DSBGA","metaDescription":"Texas Instruments TPS61050AYZGT step-up DC-DC regulator for camera flash. 1.2 A output, PWM dimming, 2 MHz switching, 12-DSBGA package.","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)","Topology":"Step-Up (Boost)","Frequency":"2MHz","Applications":"Camera Flash","Mounting Type":"Surface Mount","Package / Case":"12-UFBGA, DSBGA","lifecycle_stage":"eol_hot","Voltage - Output":"5.5V","Number of Outputs":"1","Internal Switch(s)":"Yes","Base Product Number":"TPS610","Operating Temperature":"-40°C~85°C(TA)","Voltage - Supply (Max)":"6V","Voltage - Supply (Min)":"2.5V","Supplier Device Package":"12-DSBGA","Current - Output / Channel":"1.2A (Flash)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f599e8be00b2f52162a24e899d4ed5bc.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61050AYZGT/alternatives.json"},"ai":{"faq":[{"question":"Can TPS61050AYZGT be used with a 3.7 V battery?","answer":"Yes.
