ZL9024M

Digital DC/DC PMBus 33A Module

FN8837

Rev.1.00

Dec 20, 2017

The

ZL9024M

is a 33A 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 33A of continuous output current

can be delivered without a need of airflow or a heatsink.

The thermally enhanced HDA module is capable of

dissipating heat directly into the PCB.

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.
