At 1.25 MHz the inductor and output capacitor shrink — a 4.7 µH inductor and 10 µF ceramic output cap are typical — but switching losses in the internal NPN switch rise, so efficiency drops a few points at light load. At 600 kHz the inductor is roughly twice the value, but the efficiency curve peaks higher, especially above 50% load. The trade-off is between board area and thermal budget. No synchronous rectifier is used — the external Schottky diode (e.g., a 3 A, 20 V part) handles the catch current. The diode's forward drop and reverse recovery add to the loss; a low-Vf Schottky keeps the efficiency above 85% in the mid-load range. The diode selection directly affects the output ripple and the switch voltage stress during the off-time. ## Input and output voltage range — where it fits The adjustable output goes from a 1.26 V reference up to 17.5 V — that covers 12 V rails, 15 V bias lines, and OLED/VFD supplies. The 17.5 V maximum is set by the switch breakdown, not the feedback divider; keep the output below that to avoid avalanche stress on the switch. ## Package and thermal — the exposed pad is the heatsink The 14-WFDFN with exposed pad (4x4 mm WSON) routes the thermal path through the die attach pad. Solder the pad to a copper plane on the top layer and use vias to a ground plane on the inner or bottom layer — the datasheet recommends a 1 in² copper area for full 2.55 A switch operation at high ambient. Without that thermal relief, the junction temperature climbs above the 125 °C absolute maximum under sustained heavy load.","metaTitle":"TI LM2700LD-ADJ/NOPB Boost Regulator, 2.55A Switch, 14-WSON","metaDescription":"Texas Instruments LM2700LD-ADJ/NOPB step-up DC-DC converter, 2.55A switch, 600kHz/1.25MHz, adjustable output to 17.5V, -40 to 125°C, 14-WSON, active, RoHS3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Up","Topology":"Boost","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"14-WFDFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Output":"2.55A (Switch)","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"600kHz, 1.25MHz","Operating Temperature":"-40°C ~ 125°C (TJ)","Synchronous Rectifier":"No","Voltage - Input (Max)":"12V","Voltage - Input (Min)":"2.2V","Voltage - Output (Max)":"17.5V","Supplier Device Package":"14-WSON (4x4)","Voltage - Output (Min/Fixed)":"1.26V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.63","priceTiers":[{"qty":1,"price":"$4.63000","currency":"USD"},{"qty":10,"price":"$4.16300","currency":"USD"},{"qty":25,"price":"$3.93520","currency":"USD"},{"qty":100,"price":"$3.41060","currency":"USD"},{"qty":250,"price":"$3.23564","currency":"USD"},{"qty":500,"price":"$2.90334","currency":"USD"},{"qty":1000,"price":"$2.47500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/c508314f0df534ecdbed24ddefbbf730.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM2700LD-ADJ%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional alternative to LM2700LD-ADJ/NOPB?","answer":"The TPS65261RHBT is a different device entirely — it is a triple-output step-down (buck) converter, not a boost.
