SUMMIT MICROELECTRONICS SIX-CHANNEL CONTROLLER DELIVERS HIGHLY ACCURATE INTELLIGENT POWER MANAGEMENT

Margining and sequencing supplement the device's closed-loop active control capability

FIGURE 1 

SMM665 Used for Active DC Output Control, Environmental Monitor, Margin test and Sequencing. The example here shows two the SMM665 controlling two DC/DC converters; up to six can be handled by the product.


FIGURE 2 

Waveform showing the SMM665 Sequencing and Margining of Four Channels. Up to Six Channels can be handled by the SMM665.

Time/Horizontal division = 400mS
