60 V, 1 A synchronous buck converter, fixed 3.3 V output, 600 kHz, 3 x 2 mm TDFN-10
The Analog Devices (Maxim) MAX17502EATB+T is the fixed 3.3 V, 600 kHz member of the MAX17502 family of high-voltage synchronous step-down converters with integrated MOSFETs. It runs from 4.5 V to 60 V input and delivers up to 1 A, with internal compensation, no external Schottky diode, a RESET output and programmable EN/UVLO. It is used in industrial process control, HVAC and building control, telecom and 24 V field-powered equipment. Lead times on this part are extended; Cerametronics helps buyers locate traceable stock and evaluate compatible options.

Quality & Traceability
Cerametronics is ISO 9001 certified and products are RoHS compliant, with counterfeit screening and full traceability on every shipment. A Certificate of Conformance is available on request. For allocation-sensitive or high-risk lots, independent third-party lab verification can be arranged — just flag it on your RFQ. Any lot that fails incoming inspection is quarantined and never shipped.
FAQ
How do the MAX17502 E, F, G and H versions differ?
Per the ADI datasheet: E = 3.3 V fixed, 600 kHz (TDFN-10); F = 5 V fixed, 600 kHz (TDFN-10); G = adjustable, 600 kHz (TDFN-10); H = adjustable, 300 kHz (TSSOP-14). E, F and G share the same TDFN footprint, but the G version needs an external feedback divider to set 3.3 V.
What does the +T suffix mean?
"+" marks the lead-free/RoHS package and "T" means tape and reel. MAX17502EATB+ is the same device in non-reel packaging.
