The MAX5974AETE+ is a versatile active-clamped, current-mode PWM controller designed for forward converters in Power-over-Ethernet (PoE) powered device (PD) applications. It supports a wide input voltage range of 7V to 26V and features a programmable switching frequency from 100kHz to 600kHz, with synchronization up to 1.2MHz.
Key features include programmable dead time for zero-voltage switching (ZVS), frequency foldback for light-load efficiency, and a unique feed-forward maximum duty-cycle clamp. The MAX5974A/B variants offer regulation without an optocoupler, utilizing an internal error amplifier with a 1% reference. The device includes comprehensive fault protection such as cycle-by-cycle peak current-limit, output short-circuit protection with hiccup mode, and reverse current limit.
Packaged in a compact 16-pin TQFN (3x3) with an exposed pad, the MAX5974AETE+ is suitable for surface mount applications. It is rated for operation over a temperature range of -40°C to 85°C.
This controller is well-suited for applications like IP phones, wireless access nodes, and security cameras requiring efficient DC-DC conversion.
