OVERVIEW
The ZL9024M uses ChargeMode™ control architecture, which responds to a transient load within a single switching cycle. The ZL9024M comes with a preprogrammed configuration for operating in a pin-strap mode; output voltage, switching frequency, and device SMBus address can be programmed with external resistors. More configurations such as soft-start and fault limits, can be easily programmed or changed using PMBus compliant serial bus interface. PMBus can be used to monitor voltages, current, temperatures, and fault status. The ZL9024M is supported by PowerNavigator™ software, a Graphical User Interface (GUI) that can be used to configure modules to a desired solution.
The ZL9024M is available in a 40 Ld compact 17mmx19mm HDA module with a very low profile height of 3.55mm, suitable for automated assembly by standard surface mount equipment. The ZL9024M is RoHS compliant by exemption.

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.
