Intersil introduced its ZL9101M fully encapsulated digital DC/DC power module for PoL power management in servers, telecommunications, networking, and storage equipment. This variable output step-down PMBus-compliant digital power supply includes a high performance digital PWM controller, power MOSFETs, an inductor, and the passive components required for a complete DC/DC power solution. The module operates over a wide input voltage range and supports an output voltage range of 0.6 V to 4 V, which can be set by external resistors or via PMBus. This power module is capable of delivering 12 A. Only bulk input and output capacitors are needed to finish the design. The output voltage can be precisely regulated to as low as 0.6 V with ±1 percent output voltage regulation over line, load, and temperature variations.
