The ZL9006M is a 6A adjustable output, step-down synchronous 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 ZL9006M 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 ZL9006M functions as a switch mode power supply with added benefits of auto compensation, programmable power management features, parametric monitoring, and status reporting capabilities.

The ZL9006M is packaged in a thermally enhanced, compact (17.2mmx11.45mm) and low profile (2.5mm) overmolded High-Density Array (HDA) package module suitable for automated assembly by standard surface mount equipment. The ZL9006M is RoHS compliant.

Figure 1 represents a typical implementation of the ZL9006M. For PMBus operation, it is recommended to tie the Enable pin (EN) to SGND.
