DATASHEET
ZL9117M
Digital DC/DC PMBus 17A Module
The
ZL9117M
is a 17A, 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 eliminate
the need for manual compensation design work. The ZL9117M
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. This high-efficiency power
module is capable of delivering 17A. 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 ZL9117M features auto-compensation, internal soft-start,
auto-recovery overcurrent protection, an enable option, and
prebiased output start-up capabilities.
The ZL9117M is packaged in a thermally enhanced, compact
(15mmx15mm) and low profile (3.5mm) overmolded QFN
package module suitable for automated assembly by standard
surface mount equipment. The ZL9117M is RoHS compliant.
Figure 1
represents a typical implementation of the ZL9117M.
For PMBus operation, it is recommended to tie the Enable pin
(EN) to SGND.
