The MAX5074 evaluation kit (EV kit) is a fully assembled and tested circuit board that contains a high-efficiency, 14W, forward DC-DC converter in the industry-standard 1/8th-brick footprint. The circuit is configured for a 12V output voltage and provides up to 1.2A of current. Power for the circuit can be provided from a 36V to 72V DC source as well as sources used in the telecom/datacom markets, industrial environments, and in automotive 42V power systems. The EV kit uses the MAX5074 IC that includes internal power MOSFETs. High efficiency up to 85% at 1.2A is achieved using an internally clamped two-transistor topology. Part of the efficiency improvement is due to the recovery of stored leakage and magnetizing inductance energy at the primary side. The MAX5074 is programmed to switch at 250kHz. The undervoltage lockout (UVLO) threshold is programmed to 30V and the integrated fault protection provides effective fault management. Output galvanic isolation is achieved by an optocoupler and the surface-mount power transformer.
