Three independent outputs each sink 30 mA, controlled via PWM dimming at a 500 kHz switching frequency. Housed in a 16-bump DSBGA (2.5 x 2.12 mm), this is a wafer-level chip-scale package. The 0.5 mm pitch and 0.3 mm ball diameter mean the board-side landing pattern is tight — a 2-layer PCB with micro-vias handles fan-out, but the pad layout must match the TI recommended footprint to avoid solder bridging under reflow. The DSBGA's thermal resistance is dominated by the PCB copper area under the package — no exposed pad, so the heat flows through the solder balls into the board traces. ROHS3 compliant per, with no halogen or lead restrictions beyond the standard exemption set.","metaTitle":"Texas Instruments LM3532TMX-40A/NOPB LED Driver, 40V Boost","metaDescription":"Texas Instruments LM3532TMX-40A/NOPB DC-DC regulator, boost topology, 3 outputs at 30mA each, 40V output, PWM dimming, 500kHz, active production, ROHS3","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"DC DC Regulator","Dimming":"PWM","Package":"Bulk","Topology":"Step-Up (Boost)","Frequency":"500kHz","Applications":"Backlight","Mounting Type":"Surface Mount","Package / Case":"16-WFBGA, DSBGA","lifecycle_stage":"eol_hot","Voltage - Output":"40V","Number of Outputs":"3","Internal Switch(s)":"Yes","Operating Temperature":"-40°C ~ 125°C (TJ)","Voltage - Supply (Max)":"5.5V","Voltage - Supply (Min)":"2.7V","Supplier Device Package":"16-DSBGA (2.5x2.12)","Current - Output / Channel":"30mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.62","priceTiers":[{"qty":487,"price":"$0.62000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/bb5a12e4ef8cfa5582e0590acdec904f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3532TMX-40A%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"How do I get current pricing and availability for LM3532TMX-40A/NOPB?","answer":"Submit an RFQ against your BOM quantity."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3532TMX-40A-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3532TMX-40A-NOPB when reusing this data.
