It delivers up to 7.5 W with a wide input range of 4.2 V to 60 V, making it a fit for industrial and automotive auxiliary supplies where board space is tight. Switching frequency runs between 100 kHz and 350 kHz, which lets you balance transformer size against efficiency. ## What the ratings mean for your BOM The 7.5 W output power is the total you can pull from the isolated rail. The 68% duty cycle limits how much of each switching period the primary-side switch can be on. Fault protection includes current limiting, over-temperature, over-voltage, short-circuit, and UVLO — all on-chip. That means you can skip external supervisor ICs for most designs, saving board area and BOM cost. The -40°C to 125°C operating range qualifies it for outdoor telecom cabinets, motor drives, and under-hood automotive auxiliary supplies. No commercial-grade derating needed for harsh environments. ## Active, no LTB risk Marked as Active with ROHS3 compliance. No end-of-life notice or last-time-buy window to track.","metaTitle":"MAX17691AATC+ Isolated Flyback Switching Regulator, 7.5 W","metaDescription":"MAX17691AATC+ isolated flyback switching regulator from Analog Devices. 7.5 W output, 4.2V–60V input, -40°C to 125°C.

The 7.5 W output capability and wide input range (4.2 V to 60 V) make it suitable for a 5 V / 1.5 A isolated flyback design.

The MAX17691AATC+ integrates the switch, so a direct pin-compatible swap is not possible without board changes.
