The ISL70003SEHEV1Z evaluation board is designed to evaluate the performance of the ISL70003SEH, a TID and SEE hardened 6A synchronous buck regulator IC with integrated MOSFETs intended for space applications. For more detailed information about the ISL70003SEH, please refer to the datasheet. The ISL70003SEHEV1Z evaluation board accepts a nominal input voltage of 12V and provides a regulated output voltage of 3.3V with output current ranging from 0A to 6A. The output can be quickly adjusted to an alternate voltage using the onboard potentiometer. A PGOOD (Power Good) signal goes high and lights a green LED to indicate that the output voltage is within a ±11% typical regulation window. A toggle switch (SW1) is provided to conveniently enable or disable the output voltage. The ISL70003SEHEV1Z evaluation board can be set to run from the nominal 500kHz or 300kHz internal oscillator of the ISL70003SEH or synchronized to an external clock. The evaluation board also features a load transient generator to evaluate the dynamic performance of the ISL70003SEH.
