The MAX5069A evaluation kit (EV kit) is a fully assembled and tested circuit board that contains a high-efficiency, 120W isolated push-pull DC-DC converter. The circuit is configured for a +12V output voltage and provides up to 10A of output current. The circuit can be powered from either a +36V to +72V or -36V to -72V DC source, as used in the telecom/datacom markets, industrial environments, or in automotive 42V power systems. High efficiency up to 91% is achieved at 10A while using two n-channel primary-side MOSFETs switching at up to 90% combined duty cycle. On the secondary-side, reduced output-voltage ripple and high efficiency is achieved through full-wave rectification from a centertapped planar transformer. Galvanic isolation up to 500V is achieved by an optocoupler and the planar surfacemount transformer. The optocoupler helps in providing isolated secondary-side regulation. Operation at 500kHz allows the use of small magnetics and output capacitors. A SYNC input is featured to ease synchronization to an external clock. The EV kit provides cycle-by-cycle current-limit protection. Additional steadystate fault protection is provided by the integrating fault protection that reduces average dissipated power during continuous overload conditions. The MAX5069A also has a programmable input undervoltage lockout (UVLO) for protection during brownout conditions. The EV kit may be used to evaluate other versions of the MAX5069. |
