The MAX20743 is a fully integrated, highly efficient switching regulator with PMBus™ for applications operating from 4.5V to 16V and requiring up to 35A maximum load. This single-chip regulator provides extremely compact, high-efficiency power delivery solutions with high-precision output voltages and excellent transient response for networking, datacom and telecom equipment.

The IC offers a broad range of programmable features through either the PMBus or through a capacitor and resistor connected to a dedicated programming pin. Using this feature, the operation can be optimized for a specific application, reducing the component count and/or setting appropriate trade-offs between the regulator’s performance and system cost. Ease of programming enables using the same design for multiple applications.

The IC includes protection and telemetry features. Positive and negative cycle-by-cycle overcurrent protection and overtemperature protection ensure a rugged design. Input undervoltage lockout shuts down the device to prevent operation when the input voltage is out of specification. A status pin provides an output signal to show that the output voltage is within range and the system is regulating.

USB-to-PMBus Interface Dongle for Power Products

Product Detail

The MAXPOWERTOOL002# is an interface adapter between a host PC (IBM™-compatible) and Analog Devices' PMBus compatible eval boards for power solutions such as hot swaps, 12V multiphase controllers, and 12V point of load devices. The interface to the host PC is a standard type-A to mini-B USB cable. The interface to the eval board is through a 16-pin ribbon cable that carries the PMBus commands.

The MAXPOWERTOOL002# is intended to be used with Analog Devices’s Digital PowerTool GUI, and it works with the following devices: MAX20751, MAX20754, MAX20710, MAX20730, MAX20743, MAX20734, MAX20796, MAX20810, MAX20815, MAX16550, MAX16545B/C.

Product Detail

The MAX20743 Evaluation Kit (EV kit) serves as a reference platform for evaluating the MAX20743 voltage regulator IC. This single-chip, integrated switching regulator provides an extremely compact, low-cost, highly efficient, fast, accurate, and reliable power-delivery solution for emerging low output-voltage applications up to 35A. Refer to the MAX20743 IC data sheet for more information.

The EV kit consists of a fully assembled and tested PCB implementation of the MAX20743. Jumper pins, test points, and input/output connectors are included for flexibility and ease of use in a wide range of applications.

The evaluation board is configured with an “edge strip” to allow high di/dt loading when evaluating the system. The +VOUT connection is on the top side, while the return (or -VOUT) is on the bottom side, directly mirroring the topside strip.

Either solder directly to the output “strip” or use the J8 terminal block to interface to a load.
