General Description
The MAX16920B evaluation kit (EV kit) is an assembled
and tested PCB used to evaluate the MAX16920B power-
management IC for automotive radios, containing three
step-down converters, one linear regulator (LDO), and an
overvoltage-protection block.
The EV kit comes with a MAX16920BATJ/V+ installed,
which is the 2.2MHz switching-frequency version. For
the 400kHz switching-frequency version, contact
the factory for free samples of the pin-compatible
MAX16920AATJ/V+. Additional capacitors and inductors
are provided in the EV kit for the MAX16920A.
