Evaluates: MAX5022 19-2073 Rev 3 4/05 MAX5022 Evaluation Kit General Description Features The MAX5022 evaluation kit (EV kit) is a fully assembled 85VAC to 265VAC or 120VDC to 375VDC Input and tested 5W flyback-converter circuit board. The Range power supply is configured for an isolated +5VDC out- Isolated Output Voltage: +5VDC at 1A put voltage that can supply up to 1A of current. The line input voltage range is from 85VAC to 265VAC or Input-to-Output Isolation Up to 4500VDC 120VDC to 375VDC. Fully Assembled and Tested The MAX5022 EV kit demonstrates high efficiency up to 80% at 262kHz switching frequency. This high efficiency Efficiency Up to 80% is achieved by using a single transistor (MOSFET), 2% Output Voltage Regulation Over Line and flyback-converter topology providing output power up to Load 5W. The surface-mount transformer has a tertiary wind- ing to power the MAX5022 IC after startup. An optocou- pler 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 connect- Ordering Information ed to it must be careful to follow safety procedures PART TEMP RANGE IC PACKAGE appropriate for working with high-voltage electrical equipment. MAX5022EVKIT 0C to +70C 6 SOT23-6 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 component debris at high velocity. Operate this kit with care to avoid possible personal injury.
