TTL “1”or OPEN – will turn on the power supply (For normal operation leave the signal not connected). TTL “0” or short– will turn off the power supply. SYNC signal The SYNC signal is used to allow the power supply frequency to sync with the system frequency. The system frequency should be 250 kHz ± 10 kHz. When not connected the power supply will work at 250 kHz ± 10 kHz. SIGNAL RTN The SIGNAL RTN is used as a return path for SYNC and INHIBIT signals. This pin is referenced to VIN RTN. OUT 1 SENSE The SENSE is used to achieve accurate load regulation at load terminals. This is done by connecting the pins directly to the load terminals. The remote sense correction function is limited to voltage drop between converter’s output and load terminals of 2% to 5%, or up to 0.5V, the least of the two. When not used, connect OUT 1 SENSE to OUT 1 and - OUT 1 SENSE RTN to - OUT 1. Do not leave SENSE and SENSE RTN pins unconnected. These pins can be tied internally to avoid external connection, if function is not required – consult factory OUT 2 SENSE The SENSE is used to achieve accurate load regulation at load terminals. This is done by connecting the pins directly to the load terminals. The remote sense correction function is limited to voltage drop between converter’s output and load terminals of 2% to 5%, or up to 0.5V, the least of the two. When not used, connect OUT 2 SENSE to OUT 2 and - OUT 2 SENSE RTN to - OUT 2 Do not leave SENSE and SENSE RTN pins unconnected. These pins can be tied internally to avoid external connection, if function is not required – consult factory.
