DATASHEET
Digital DC/DC PMBus 10A Power Module
ZL9010M
The ZL9010M is a 10A adjustable output, step-down
synchronous 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 ZL9010M 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.
The ZL9010M functions as a switch mode power supply with
added benefits of auto compensation, programmable power
management features, parametric monitoring and status
reporting capabilities.
The ZL9010M is packaged in a thermally enhanced, compact
(17.2mm x 11.45mm) and low profile (2.5mm) overmolded
high-density array (HDA) package module suitable for
automated assembly by standard surface mount equipment.
The ZL9010M is RoHS compliant.
Figure 1 represents a typical implementation of the ZL9010M.
For PMBus operation, it is recommended to tie the Enable pin
(EN) to SGND.
