Figure 1: SenSe connectionS anD trim table – Single output moDelS SenSe anD trim Single output models provide sense to maintain voltage at the load. The converters output voltage can also be trimmed up. See Figure current Sharing anD parallel operation For increased power parallel up to 3 converters. The maximum recommended power is 70% of the total available power. Multiple MFL converters may be used in parallel to drive a common load. Only single output models with SENSE and SNS RTN can be used in the share mode. In this mode of operation the load current is shared by two or three MFL converters. In current sharing mode, one MFL converter is designated as a master. The SL aVE pin (pin 1 1) of the master is left unconnected and the MSTR/INH2 pin (pin 12) of the master is connected to the SL aVE pin (pin 1 1) of the slave units. The units designated as slaves have the MSTR/INH2 pin (pin 12) connected to the SNS RTN pin (pin 9) of the master unit. Figure 2 on page 3 shows the typical setup for two or three units in parallel. a second slave unit may be placed in parallel with a master and slave; this requires the TRI pin (pin 3) of the master unit to be connected to the SNS RTN pins (pin 9), per Figure 2 on page In current sharing mode, the converters function as a current source. For this reason it is important that their outputs be connected to the common ground at all times to prevent an excessively high voltage at their outputs.
