Intersil ISL70003ASEHEV2Z User Manual

ISL70003ASEHEV2Z Evaluation Board User Guide
The ISL70003ASEHEV2Z evaluation board is designed to
demonstrate the performance of the
as a 12V input to 3.3V output, 6A output current POL regulator,
with a significantly reduced size footprint compared to the
ISL70003ASEHEV1Z platform, making it ideal for wiring into
an existing circuit. For more detailed information, please refer
to the ISL70003ASEH datasheet.
The ISL70003ASEHEV2Z 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. There is a green
LED indicating PGOOD. The input voltage and output voltage
presets can be changed to alternate voltages by resistor
substitutions.
The ISL70003ASEHEV2Z evaluation board is configured to run
from the nominal 300kHz internal oscillator of the
ISL70003ASEH.
