Key Features
- Wide 4.5 V to 36 V input range enabling operation across automotive, telecom, and industrial supply rails
- Up to 1 MHz switching frequency allowing use of smaller external inductors and capacitors to reduce solution size
- Current-mode PWM control with 100 mA gate drive for precise cycle-by-cycle current limiting in isolated and non-isolated topologies
Applications
The MAX17597ATE+ is designed for use in isolated flyback and forward converters in industrial and telecommunications equipment where a wide input voltage range of 4.5 V to 36 V is required. Its 1 MHz switching frequency supports compact magnetics design in distributed power architectures, point-of-load regulators, and battery-powered systems. The 16-pin TQFN package and integrated protection features make it well suited for space-constrained power supply modules.

Frequently Asked Questions
What input voltage range does the MAX17597ATE+ support, and how does that affect design flexibility?
The MAX17597ATE+ operates over a 4.5 V to 36 V input range, enabling a single design to cover industrial 24 V bus, automotive 12 V, and telecom 48 V (with pre-regulation) applications without redesigning the controller stage, reducing BOM count across product variants.
At what maximum switching frequency can the MAX17597ATE+ operate, and what benefit does that provide?
The MAX17597ATE+ supports switching frequencies up to 1 MHz, allowing designers to use smaller inductors and output capacitors, which reduces PCB footprint and component cost in compact power supplies rated up to 36 V input.
How does the MAX17597ATE+ protect the power stage during fault conditions?
The MAX17597ATE+ uses cycle-by-cycle current-mode control with a 100 mA gate drive output to enforce per-cycle current limiting, preventing inductor saturation and transistor overcurrent events during load transients or short-circuit conditions in flyback and forward converter designs.
What package does the MAX17597ATE+ use, and what are its board-space implications?
The MAX17597ATE+ is housed in a 16-pin TQFN (Quad Flat No-Lead) package measuring 3 mm x 3 mm x 0.75 mm, making it suitable for high-density power supply PCBs where minimizing controller footprint is a priority alongside thermal dissipation.
