ZL9010M Datasheet, PDF (1/30 Pages) Intersil Corporation – Digital DC/DC PMBus 10A Power Module

Digital DC/DC PMBus 10A Power Module
ZL9010M
The ZL9010M is a 10A variable output, step-down
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) over-molded
high-density array (HDA) package module suitable for
automated assembly by standard surface mount equipment.
The ZL9010M is Pb-free and 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.
