The ASIC contains a Power over Ethernet Powered Device (PoE-PD) and a flexible and configurable DC-DC controller. This integrated current mode DC-DC controller facilitates isolated and non-isolated fly-back, forward and buck converter topologies. It has all the features necessary for a flexible, robust and highly efficient design including programmable switching frequency, duty cycle up to 80 percent, slope compensation, and soft start-up. The datasheet can be downloaded here: NCP1083-D.

FEATURES:

• PoE-PD supporting IEEE802.3af and IEEE802.3at standards
• PWM DC-DC controller for flyback, buck and forward converters
• Auxiliary Supply Support
• Current slope compensation circuit
• Over-temperature protection and programmable UVL (under voltage lockout)
• Component part number NCP1083
• 4kV HBM ESD
• Temperature range -40°C to 85°C
• 0.35um BCD technology with HV extension (I3T80)
