FAQ

What is the primary function of the KIT34717EPEVBE evaluation board?

The KIT34717EPEVBE evaluation board demonstrates the MC34717 5.0 A, 1.0 MHz synchronous buck DC-DC converter. It provides a ready-to-use platform for validating input/output performance, thermal behavior, and protection features. Engineers use KIT34717EPEVBE to verify design margins before integrating the MC34717 into final PCB layouts.

Does KIT34717EPEVBE support adjustable output voltage?

Yes, KIT34717EPEVBE supports output voltage adjustment from 0.8 V to 5.5 V using an external resistor divider on the FB pin. The board includes test points and solder jumpers to modify feedback network values, allowing precise tuning of the regulated output for different load requirements without redesigning the board.

What input voltage range is validated on the KIT34717EPEVBE?

KIT34717EPEVBE is validated for operation across 4.5 V to 28 V input, matching the MC34717's specified operating range. This enables testing under nominal 5 V, 12 V, and 24 V industrial bus conditions, including brown-out and surge scenarios typical in factory automation and transportation equipment.

Can KIT34717EPEVBE be synchronized to an external clock?

Yes, KIT34717EPEVBE exposes the SYNC pin of the MC34717, allowing synchronization to an external 1.0 MHz clock source. This feature helps reduce EMI in multi-converter systems by aligning switching edges and avoids beat frequencies that could interfere with sensitive analog or RF sections in the same system as KIT34717EPEVBE.

Is KIT34717EPEVBE RoHS compliant?

Yes, KIT34717EPEVBE is EU RoHS compliant, as confirmed in the official Freescale declaration dated April 2, 2007. All components and PCB materials used in KIT34717EPEVBE meet Directive 2002/95/EC requirements for restriction of hazardous substances, supporting environmental compliance in commercial and industrial end products.
