The MAX15000A evaluation kit (EV kit) is a fully assembled and tested circuit board that contains a 9W flyback DC-DC converter. The circuit is configured for +5V and +15V output voltages and provides up to 1.5A and 100mA of current at each respective output. Power for the circuit can be provided from either a +36V to +72V or a -36V to -72V DC source.
High efficiency up to 81% is achieved using a flyback DC-DC converter topology. The surface-mount transformer provides up to 1500V galvanic isolation for both outputs. Low cost is achieved through the use of primary-side regulation while undervoltage lockout (UVLO) and digital soft-start provide for a robust 9W isolated power supply.
Operation at 350kHz allows the use of small magnetics and output capacitors.
Warning: The MAX15000A EV kit is designed to operate with high voltages. Dangerous voltages are present on this EV kit and on equipment connected to it. Users who power up this EV kit or power the sources connected to it must be careful to follow safety procedures appropriate to working with high-voltage electrical equipment.
Under severe fault or failure conditions, this EV kit may dissipate large amounts of power, which could result in the mechanical ejection of a component or of component debris at high velocity. Operate this kit with care to avoid possible personal injury.
