SMM-105-02-S-D-02

The SMM-105-02-S-D-02 actively controls the output voltage level of a DC/DC converter that uses a Trim or VADJ/FB pin to adjust the output. An Active DC Output Control(ADOCTM) feature is used during normal operation to maintain extremely accurate settings of supply voltages and, during system test, to control margining of the supplies using I2C commands. Total accuracy with a ±0.1% external reference is ±0.2%, and ±0.5% using the internal reference. The SMM-105-02-S-D-02 can margin supplies with either positive or negative trim pin control within a range of 0.3V to VDD. The SMM-105-02-S-D-02 supply can be from 12V, 8V, 5V or 3.3V to as low as 2.7V to accommodate any intermediate bus supply.

Features of the SMM-105-02-S-D-02 can be summarized as:(1)extremely accurate (±0.1%) active DC output control;(2)ADOC automatically adjusts supply output voltage level under all DC load conditions;(3)capable of margining supplies with trim inputs using either positive or negative trim pin control;(4)wide margin/ADOC range from 0.3V to VDD;(5)uses either an internal or external VREF;(6)operates from any intermediate bus supply from 8V to 15V and from 2.7V to 5.5V;(7)programmable START and READY pins;(8)two programmable general purpose monitor sensors-UV and OV with FAULT output flag;(9)general purpose 1k EEPROM with write protect.And SMM-105-02-S-D-02 can be used in in-system test and control of Point-of-Load (POL) Power Supplies for Multi-voltageProcessors, DSPs and ASICs and enterprise and edge routers, servers, storage area networks.
