LMZ10500SILEVM: 1.8V @ 650mA, 2.7 ~ 5.5V in

Summary

The LMZ10501 and LMZ10500 Evaluation Board is configured for 1.8V output voltage from 2.7V to 5.5V input. The resistor voltage divider RT and RB set the output voltage. The external capacitor CVC bypasses the VCON pin and provides additional soft start time. For component selection and device information details, see the device-specific data sheet.

The board features additional component footprints for various device enabling schemes and AC signal injection terminals for feedback loop measurements. The evaluation board with its default Bill of Materials offers great EMI performance, complying with the EN55022 Class B radiated emissions standard.
