Product Details

The MAX5003 evaluation kit (EV kit) provides a regulated 5V output voltage up to 1A while operating from a +36V to +72V input voltage.

The MAX5003 EV kit is a fully assembled and tested surface-mount printed circuit (PC) board. It comes with the output voltage set to 5V. This EV kit is configured as a flyback converter, and can easily be configured for either isolated or nonisolated operation by selecting the state of a mechanical switch. Additionally, for systems in which the input and output ground references are not at the same potential and for which isolation is not desired, the user has the option to install a level-shifter (not supplied) in the controller feedback loop.

WARNING: 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.
