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.

MAX16920B Evaluation Kit Evaluates: MAX16920A/MAX16920B LDOA The output voltage on the linear regulator (LDOA) is set at 5V and can be accessed from the OUTA PCB pad on the EV kit. The output can be enabled or disabled by placing a shunt in the appropriate position on jumper JU3 (see Table 1). To enable LDOA, place a shunt in the 1-2 position on JU3. To disable LDOA, place a shunt in the 2-3 position on JU3. LED D3 indicates that the output of LDOA is in the correct regulation range.
