Digital DC/DC PMBus 6A Power Module
ZL9006M
Features
The ZL9006M is a 6A variable output, step-down
• Complete digital switch mode power supply
• Auto compensating PID filter
• ±1% Output Voltage Accuracy
• External synchronization
PMBus-compliant digital power supply. Included in the module
is a high-performance digital PWM controller, power MOSFETs,
an inductor, and all the passive components required for a
highly integrated DC/DC power solution. This power module has
built-in auto-compensation algorithms, which eliminates the
need for manual compensation design work. The ZL9006M
operates over a wide input voltage range and supports an
output voltage range of 0.6V to 3.6V, which can be set by
external resistors or via PMBus. Only bulk input and output
capacitors are needed to finish the design. The output voltage
can be precisely regulated to as low as 0.6V with ±1% output
voltage regulation over line, load, and temperature variations.
• Output voltage tracking
• Current sharing and phase interleaving
• Programmable sequencing (delay and ramp time)
• Snapshot™ parametric capture
• PMBus compliant
Applications
• Server, telecom, and datacom
• Industrial and medical equipment
• General purpose point of load
The ZL9006M functions as a switch mode power supply with
added benefits of auto compensation, programmable power
management features, parametric monitoring, and status
reporting capabilities.
The ZL9006M is packaged in a thermally enhanced, compact
(17.2mmx11.45mm) and low profile (2.5mm) over-molded
High-Density Array (HDA) package module suitable for
automated assembly by standard surface mount equipment.
The ZL9006M is Pb-free and RoHS compliant.

Figure 1 represents a typical implementation of the ZL9006M.
For PMBus operation, it is recommended to tie the Enable pin
(EN) to SGND.
