com 19-5331; Rev 0; 6/10 Active-Clamped, Spread-Spectrum, Current-Mode PWM Controllers General Description The MAX5974_ provide control for wide-input-voltage, active-clamped, current-mode PWM, forward converters in Power-over-Ethernet (PoE) powered device (PD) applications.
The MAX5974A/MAX5974C are well-suited for universal or telecom input range, while the MAX5974B/ MAX5974D also accommodate low input voltage down to 10.
5V.
The devices include several features to enhance supply efficiency.
The AUX driver recycles magnetizing current instead of wasting it in a dissipative clamp circuit.
Programmable dead time between the AUX and main driver allows for zero-voltage switchi...
