To use this feature, connect this pin directly to load 1's positive terminal. If this function is not required, short SENSE 4 to OUT 4 (pins 14, 31 and 32) as close as possible to the connector. SENSE 4 RTN (pin 24) The SENSE 4 RTN line is used to achieve accurate voltage regulation at load terminals. To use t his feature, connect this pin directly to load's negative terminal. If this function is not required, short SENSE 4 RTN to OUT 4 RTN (pins 15, 16, 33 and 34) as close as possible to the connector. This signal is referenced to OUTS 4, 5, 6 RTN. Note: The use of remote sense has a limit of voltage dropout between the converter's output and the load's terminals of approximately 5% of nominal output voltage or 0.5 V – the lesser of the two. INHIBIT (pin 22) The INHIBIT signal is used to turn the power supply ON and OFF. TTL “1” or OPEN – Power supply active (output turned on). TTL “0” or SHORT to SIGNAL RTN – Power supply inhibited (output turned off). If this function is not required, leave this pin unconnected. This signal is referenced to SIGNAL RTN (pin 21) SYNC (pin 23) The SYNC signal is used to synchronize the power supply's switching frequency to system's clock. Valid external clock frequency is 250 kHz ± 10 kHz, and duty cycle is 50% ± 10%. If this function is not required, leave this pin unconnected - the power supply will use its internal clock. This signal is referenced to SIGNAL RTN (pin 21) SIGNAL RTN (pin 21) Both INHIBIT and SYNC signals are referenced to this pin. This pin is referenced to INPUT RTN (pins 10, 11, 27 and 28).
