ZL9117M

Digital DC/DC PMBus 17A Module

FN7914

Rev.7.00

Jun 26, 2017

The ZL9117M is a 17A, variable output, step-down

Features

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.

• Complete digital switch mode power supply

• Fast transient response

• Auto compensating PID filter

• External synchronization

• Output voltage tracking

• Current sharing

• Programmable soft-start delay and ramp

• Overcurrent/undercurrent protection

• PMBus compliant

Applications

• Server, telecom, and datacom

• Industrial and medical equipment

• General purpose point of load

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.
