ISL73041SEHEV1Z
The ISL73041SEHEV1Z evaluation board evaluates
the performance of the radiation-hardened
ISL73041SEH
12V half-bridge GaN FET driver in an
open-loop Buck configuration. The
ISL73041SEHEV1Z evaluation board includes the
GaN FET half-bridge driver, Renesas GaN FETs, and
a Buck converter power stage inductor and output
capacitors.
For more information about the ISL73041SEH, refer

    V_OUT below 5V. Changing Power Inductor The ISL73041SEHEV1Z is populated with a 0.22µH inductor on the L1 footprint targeted for 500kHz to 1MHz switching frequency. The inductor used is a Coilcraft XAL1010-022. If the user requires using a lower switching frequency and maintaining a similar ripple current, a larger inductance must be used.
