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.
