Analog Devices Inc./Maxim Integrated MAX16712EVKIT#

Overview

MAX16712EVKIT# from Maxim Integrated is a fully assembled and tested evaluation kit for the MAX16712 dual-output, high-efficiency step-down DC-DC switching regulator IC. It supports up to 6A per output in dual-output mode or up to 12A in interleaved dual-phase mode, with input voltage range 2.7V–16V and output voltage range 0.5V–5.8V. It is used for rapid validation of power delivery in compact, high-density embedded systems such as FPGA core supplies and multi-rail processor boards.

For engineers reviewing the MAX16712EVKIT# datasheet, MAX16712EVKIT# pinout, MAX16712EVKIT# application, or MAX16712EVKIT# equivalent, this board enables fast functional verification, efficiency measurement, soft-start characterization, and dual-phase configuration testing without custom PCB development.

Technical Context

The MAX16712EVKIT# implements the MAX16712 IC in WLP28 package (package code W282D3Z+1), featuring integrated high-side and low-side MOSFETs, internal bias LDO, and dual independent control loops. It supports configurable switching frequency (1MHz default via PGM0 = 2.87kΩ), selectable OCP thresholds (via PGM1/PGM2 jumpers), and flexible output enable (SW1/SW2 for dual-output; EN1 only for dual-phase).

Hardware-level features include pre-validated PCB layout with optimized thermal and EMI performance, filtered sense points (J9) for low-noise efficiency measurement, dedicated test points for LX1/LX2, VOUT1/VOUT2, and input monitoring (J4/J5), plus edge connectors (J20/J27) and screw terminals for load interfacing.

FAQ

What is the primary function of the MAX16712EVKIT#?

The MAX16712EVKIT# is a ready-to-use evaluation platform for the MAX16712 dual-output step-down DC-DC regulator IC. It allows engineers to verify electrical performance-including regulation accuracy, efficiency, transient response, and dual-phase operation-without designing custom hardware. The board ships fully assembled with pre-configured 1V/1.2V outputs and supports both standalone rail testing and combined 12A dual-phase mode via simple resistor modifications.

Can the MAX16712EVKIT# be used to evaluate dual-phase operation?

Yes, the MAX16712EVKIT# supports dual-phase configuration. To enable it, users must remove R14, install a 0Ω resistor at R6 to tie SNSP2 to AVDD, short the outputs using 0Ω resistors at R44–R46, and optionally replace L1/L2 with a coupled inductor. In this mode, only rail 1's control loop remains active, and EN1/PGOOD1 manage enable and status-EN2 and PGOOD2 are disconnected per the MAX16712EVKIT# documentation.

What input and output connections does the MAX16712EVKIT# provide?

The MAX16712EVKIT# provides red/black binding posts (J1/J2) for 2.7V–16V input, edge connectors (J20 for VOUT1, J27 for VOUT2) for load connection, and screw terminals for VOUT1/VOUT2. Input voltage monitoring is accessible at J4 (VDDH) and J5 (GND); output voltages are probed at J22 (rail 1) and J23 (rail 2); switching nodes are monitored at J6 (LX1) and J7 (LX2).

How is output voltage configured on the MAX16712EVKIT#?

The MAX16712EVKIT# uses external resistor dividers to set output voltage based on the MAX16712's 0.5V internal reference. Default values yield 1.0V on rail 1 and 1.2V on rail 2. Users can modify feedback resistors (e.g., R12/R13 for rail 1, R15/R19 for rail 2) to adjust VOUT within the 0.5V–5.8V range while maintaining stability per the MAX16712 datasheet compensation guidelines.

Does the MAX16712EVKIT# include provisions for efficiency measurement?

Yes, the MAX16712EVKIT# includes J9-a dedicated 8-pin connector providing filtered, low-noise access to input supply and output sense points. It supports precise efficiency testing using 0.1% lab shunts for input/output current measurement. The board also includes input current sense resistor R2 (0.001Ω, 3W) and designated locations for external shunt placement per the evaluation kit user guide.
