REFD5043, Active-Clamped Forward, Dual-Output PD Provides High-Performance Solution for PoE Applications
Thiết kế tham khảo bởi: Analog Devices
REFD5043, Reference design for a highly efficient, active-clamped forward, dual 3.3V/8.8V output powered device (PD). The design features the MAX5969A and MAX5900 as its controllers. The design also uses the MAX5974C, which controls current-mode PWM converters and provides zero-voltage switching (ZVS) and frequency foldback to enhance supply efficiency. Using these devices, this RD is IEEE 802.3at compliant and is a high-performance, compact and cost-efficient solution for PoE and nonstandard high-power PDs. The design can also support the auxiliary input voltage to provide maximum 55W output power
