TTL “1”or OPEN – will turn on the power supply. (For normal operation leave the signal not connected.) TTL “0” – will turn off the power supply. Grounding for signal is VIN RTN pin. SYNC signal The SYNC signal is used to allow the power supply frequency to sync wit h the system frequency. SYNC frequency can be 250 ± 10 kHz, TTL level. When left open, the power supply will work at 250 ± 10 kHz (internal clock). This signal is referenced to VIN RTN pin. SENSE The SENSE is used to achieve accurate load regulations at load terminals (this is done by connecting the pins directly to the load’s terminals). The use of remote sense has a limit of voltage dropout between converter’s output and load terminals of 2-10% of voltage output. When not used connect SENSE to VOUT and SENSE RTN to VOUT RTN.
