Evaluation Kit for the MAX16930 and MAX16931

Description

The MAX16930 evaluation kit (EV kit) is a fully assembled and tested application circuit for the MAX16930 high-voltage, dual synchronous step-down controller with preboost. The EV kit is set up to provide 5V and 3.3V from an input voltage ranging from 3.5V to 36V (without preboost). The preboost circuit maintains the 10V supply rail for input voltages below 10V. Each buck rail can deliver up to 5A load current. Various jumpers are provided to help evaluate features of the MAX16930 IC.

Key Features

Dual, Synchronous Step-Down Controllers Operate at 180° Out-of-Phase to Reduce Switching Noise

Voltage Monitoring PGOOD_ Outputs
Fully Assembled and Tested

MAX14970EVKIT

Evaluation Kit for the MAX14970

Description

The MAX14970 evaluation kit (EV kit) provides a proven design to evaluate the MAX14970 dual-channel buffer. The EV kit contains four sections: an application circuit, characterization circuit, and two sets of calibration traces.

The application circuit is designed to demonstrate the device’s use in redriving serial-ATA (SATA) signals and SATA cable detection. This section of the EV kit operates from an external +5V supply that is regulated by an onboard LDO to +3.3V, which powers the device. All traces in the application circuit are 100Ω differential controlled-impedance traces.

The characterization circuit is provided for eye diagram evaluation using SMA connectors and 50Ω controlled-impedance traces. This section is powered by an external +3.3V power supply.

Key Features

Application Circuit with SATA Input/Output
Eye Diagram Test Circuit with SMA Inputs/Outputs
Calibration Traces (50Ω Load Trace and Through Trace)
Proven PCB Layout
