That simplifies the design — no oscillator timing resistor to set, no clock input to route — but it also means you cannot shift the switching harmonics away from a sensitive IF band or align the converter to a system clock. For most boost and buck-boost applications in industrial and battery gear this is not a limitation; the 300kHz fundamental is well above audio frequencies and keeps magnetics reasonably small. If your system requires frequency dithering or external sync for noise management, this part is not the fit. ## Temperature grade and environment Rated for -40°C to 85°C ambient (TA), this is a full industrial-temperature part. The 8-SOIC package is a standard footprint for rework and automated assembly alike. ## Sourcing and lifecycle The MAX1771ESA+T carries an Active lifecycle status with ROHS3 compliance. No official second-source or pin-compatible alternate is listed in the record, so dual-sourcing would require a separate qualification effort.","metaTitle":"MAX1771ESA+T Boost/Buck-Boost Controller, 300kHz, 8-SOIC","metaDescription":"Maxim MAX1771ESA+T current-mode PWM controller for boost and buck-boost topologies. 300kHz fixed frequency, 3V to 16.5V supply, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Up, Step-Up/Step-Down","Topology":"Boost, Buck-Boost","Clock Sync":"No","Output Type":"Transistor Driver","Mounting Type":"Surface Mount","Output Phases":"1","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Control Features":"Enable","Duty Cycle (Max)":"92%","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"300kHz","Operating Temperature":"-40°C ~ 85°C (TA)","Synchronous Rectifier":"No","Supplier Device Package":"8-SOIC","Voltage - Supply (Vcc/Vdd)":"3V ~ 16.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.6","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$7.60000","currency":"USD"},{"qty":10,"price":"$6.86200","currency":"USD"},{"qty":25,"price":"$6.54280","currency":"USD"},{"qty":100,"price":"$5.68100","currency":"USD"},{"qty":250,"price":"$5.42572","currency":"USD"},{"qty":500,"price":"$4.94698","currency":"USD"},{"qty":1000,"price":"$4.30866","currency":"USD"},{"qty":2500,"price":"$4.14908","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX1771.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the MAX1771ESA+T switching frequency?","answer":"The switching frequency is fixed at 300kHz.
