The LMZ10501 and LMZ10500 SIMPLE SWITCHER® nano modules are easy-to-use DC-DC solutions optimized for space-constrained applications. The LMZ10501 is capable of driving up to 1A load with excellent power conversion efficiency, line and load regulation, and EMI performance. The LMZ10500 is a 650mA version module and is pin-to-pin compatible with the LMZ10501.
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. 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 EN 55022 Class B radiated emissions standard. See datasheet for component selection and device information details.
