It integrates a transistor driver output and synchronous rectifier, which improves efficiency at higher output currents compared to asynchronous controllers. The fixed 500kHz switching frequency simplifies inductor selection and EMI filter design. With a supply range of 6V to 33V and an operating temperature range of -40°C to 125°C (TJ), it suits industrial power supplies, motor drives, and outdoor telecom equipment where wide input voltage and thermal robustness are required. ## What the key ratings mean for your BOM The 500kHz fixed switching frequency sets the inductor value and output capacitor ripple current. ## Lifecycle and sourcing posture The LM3152MHE-3.3/NOPB carries an Active product status and is ROHS3 compliant. For a BOM line that needs a synchronous buck controller with a fixed 3.3V output and a wide input range, this part is a clean, current-production choice.","metaTitle":"LM3152MHE-3.3/NOPB SIMPLE SWITCHER® Buck Controller, 500kHz","metaDescription":"TI LM3152MHE-3.3/NOPB SIMPLE SWITCHER® synchronous buck controller, 500kHz fixed frequency, 6V-33V input, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":"SIMPLE SWITCHER®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"SIMPLE SWITCHER®","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Clock Sync":"No","Output Type":"Transistor Driver","Mounting Type":"Surface Mount","Output Phases":"1","Package / Case":"14-TSSOP (0.173\\\", 4.40mm Width) Exposed Pad","lifecycle_stage":"eol_hot","Control Features":"Enable, Soft Start","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"500kHz","Operating Temperature":"-40°C ~ 125°C (TJ)","Synchronous Rectifier":"Yes","Supplier Device Package":"14-HTSSOP","Voltage - Supply (Vcc/Vdd)":"6V ~ 33V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.4","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.40000","currency":"USD"},{"qty":10,"price":"$3.95600","currency":"USD"},{"qty":25,"price":"$3.73960","currency":"USD"},{"qty":100,"price":"$3.24110","currency":"USD"},{"qty":250,"price":"$3.07484","currency":"USD"},{"qty":500,"price":"$2.75906","currency":"USD"},{"qty":1250,"price":"$2.35200","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/465c8cd9a6bb238f8e2d74e1f3e68e32.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Will the LM3152MHE-3.3/NOPB drop into a board designed for the UCC2806DWTR?","answer":"No. The UCC2806DWTR is a boost/flyback/forward controller with a 47 kHz switching frequency and a different pinout and package.
