Product Overview
The MAX5986AETE+ is an IEEE 802.3af-compliant, high-efficiency, Class 1/Class 2, PDs with integrated DC to DC converter in 16 pin TQFN package. It provides a complete power-supply solution as IEEE® 802.3af-compliant Class 1/Class 2 powered devices in a Power over Ethernet system. The device integrates the PD interface with an efficient DC to DC converter, offering a low external part count PD solution. The MAX5986A include sleep and ultra-low power modes. The PD interface provides a detection signature and a Class 1/Class 2 classification signature with a single external resistor. The PD interface also provides an isolation power MOSFET, a 60mA (max) inrush current limit and a 323mA operating current limit. The integrated step down DC-DC converter uses a peak current-mode control scheme and provides an easy-to implement architecture with a fast transient response. It operates at a fixed 215KHz switching frequency.
- Wide input voltage range from 8.7V to 60V
- Protects against overload, output short circuit, output overvoltage and overtemperature
- Integrated TVS diode withstands cable discharge event (CDE)
- PoE class 1/class 2 classification set with single resistor
- Intelligent maintain power signature (MPS) complies with IEEE 802.3af specification
- Simplified wall adapter interface
- Pass 2KV, 200m CAT-6 cable discharge event
- Sleep and ultra low power mode
- Frequency foldback for high-efficiency light-load operation, Back-bias to optimize efficiency
- Hiccup-mode runaway current limit, 49mA (typ) inrush current limit
