The MAX9959 provides all the key features of a device power supply (DPS) common to automatic test equipment (ATE) and other instrumentation. Its small size, high level of integration, and superb flexibility make the MAX9959 ideal and economical for multisite systems requiring many device power supplies.

The MAX9959 has multiple input control voltages that allow independent setting of both the output voltage, and the maximum and minimum (smallest positive or most negative) voltage or current. The MAX9959 is a voltage source when the load current is between the two programmed limits, and transitions gracefully into a precision current source/sink if a programmed current limit is reached. The output features two independently adjustable voltage clamps that limit both the negative and positive output voltage values between levels externally provided.

The MAX9959 can source voltages spanning 25V and can source currents as high as ±800mA. The DPS can support an external buffer for sourcing and sinking higher currents. Multiple MAX9959s can be configured in parallel to load-share, allowing higher output currents with greater flexibility.

The MAX9959 features operation over a wide range of loading conditions. Programmability allows optimizing of settling time, over-/undershoot, and stability. Built-in, configurable, range-change glitch-control circuits minimize output glitches during range transitions.

The MAX9959 offers load regulation of 1mV at 800mA load.

The MAX9959D features an internal 300kΩ sense resistor (RFS), between RCOMF and SENSE. The MAX9959F does not include this sense resistor. Both devices are available in the 100-pin TQFP package with an exposed pad on the top for heat removal.

Product Detail

The MAX9959 evaluation kit (EV kit) is a fully assembled and tested printed circuit board (PCB) design that evaluates the functionality of device power supply (DPS) IC MAX9959, which has 25V span output voltage and programmable current ranges up to 800mA.

The MAX9959 EV kit contains a microcontroller (MCU) that translates between the SPI interface and USB to allow the user to configure internal registers and modes with graphical user interface (GUI) software running on a PC. The EV kit includes Windows® 10-compatible software that provides a simple GUI for configuration of all the MAX9959 registers through SPI. The EV kit is fully assembled and tested at the factory.

This document provides a list of equipment required to evaluate the device, a straightforward test procedure to verify functionality, a description of the EV kit circuit, component list, circuit schematic, and artwork for each layer of the PCB. The MAX9959 EV kit PCB comes with a MAX9959DCCQ+ installed.
