The ZL9024M is a 33 A step-down DC/DC power supply module with integrated digital PWM controller, synchronous power switches, an inductor, and passives. Only bulk input and output capacitors are needed to finish the design. The 33 A of continuous output current can be delivered without a need for airflow or a heatsink, thanks to the thermally enhanced HDA module that is capable of dissipating heat directly into the PCB. The ZL9024M uses the ChargeMode control architecture, which responds to a transient load within a single switching cycle. The device 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 a PMBus compliant serial bus interface. PMBus can be used to monitor voltages, current, temperatures, and fault status. The ZL9024M is also supported by the PowerNavigator software. The ZL9024M is available in a 40 I/O compact 17 mm x 19 mm HDA module with a very low profile height of 3.55 mm, suitable for automated assembly by standard surface mount equipment.
