ZL9101M

Digital DC/DC PMBus 12A Module

Product Status: Mass Production

OVERVIEW

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 eliminate 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 through 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 prebiased 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.

For PMBus operation, it is recommended to tie the Enable pin (EN) to SGND.

Industry-Leading 10A and 15A Fully Encapsulated PMBus Power Modules

The ISL828xM hybrid digital and ISL821xM analog power modules feature integrated LDOs that enable single-supply operation. They leverage Renesas’ patented R4™ high-speed control loop architecture with inherent line voltage feed-forward, providing designers a unique combination of ultra-fast load transient response and high noise immunity. Their proprietary Grid HDA package offers unmatched electrical and thermal performance through a single-layer conductive package substrate that efficiently transfers heat from the module to the system board, and dissipates it without requiring airflow or heatsinks – even under heavy load conditions.
