This new digital power module follows Intersil’s “Power Made Simple” philosophy by providing customers with a building block that can be easily adapted to varying system power requirements. The ZL9101M is a quick and easy alternative for power solutions up to 12A, and dramatically reduces the number of discrete components and complicated external ICs required to implement a complete POL power management solution. The ZL9101M also delivers the most thermally efficient package, significantly improving system reliability.

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 complete DC/DC power solution. The ZL9101M operates over a wide input voltage range and supports an output voltage range of 0.6V to 4V, 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 internal 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) over-molded QFN package module suitable for automated assembly by standard surface mount equipment. The ZL9101M is Pb-free and RoHS compliant.
