The ZL9101M is a 12A, 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 ZL9101M

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 12A. 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 ZL9101M features auto compensation, internal soft-start,

auto-recovery overcurrent protection, an enable option, and

pre-biased output start-up capabilities.

The ZL9101M 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 ZL9101M is RoHS compliant.
