The MAX5022 evaluation kit (EV kit) is a fully assembled and tested 5W flyback converter circuit board. The power supply is configured for an isolated +5VDC output voltage that can supply up to 1A of current. The line input voltage range is from 85VAC to 265VAC or 120VDC to 375VDC.
The MAX5022 EV kit demonstrates high efficiency up to 80% at 262kHz switching frequency. This high efficiency is achieved by using a single transistor (MOSFET),
flyback-converter topology providing output power up to 5W. The surface-mount transformer has a tertiary winding to power the MAX5022 IC after startup. An optocoupler along with the transformer provide input-to-output isolation up to 4500VDC.
Warning: The MAX5022 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 the power sources connected to it must be careful to follow safety procedures appropriate for 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.
