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 IN signal The SYNC IN 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. SYNC OUT signal The SYNC OUT signal is a buffered clock used to synchronize other units to the switching frequency of this unit. The signal amplitude is 12V. It is recommended to source and sink up to 1A on this pin. PAR IN signal The PAR IN signal is used to connect the power supply in parallel to other power supplies and have them almost equally divide the power between one another. All the power supplies should connect PAR IN signals together except the master unit where the PAR OUT signal connects to all the PAR IN signals. PAR OUT signal The PAR OUT signal is used to connect the power supply in parallel to other power supplies and have them almost equally divide the power between one another. The master unit connects the PAR OUT signals to all PAR IN pins of the slave units. VLTG CAL signal The VLTG CAL signal is used to control and adjust the output voltage of the power supply by up to ±5%. The calibration upwards is performed by connecting a resistor between this pin to SENSE pin. The calibration downwards is performed by connecting a resistor between this pin to SENSE RTN pin. Use a 1M Ω potentiometer set to full resistance and slowly decrease resistance until required output voltage reached. CRNT LMT CAL signal The CRNT LMT CAL signal is used to adjust the output current limit of the power supply. SIGNAL RTN The SIGNAL RTN is referred to the output. This is used as grounding for all signals. SENSE The SENSE is used to achieve accurate load regulations at load terminals (thi s 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 up to 0.5V. When not used connect + SENSE to +VOUT and –SENSE to –VOUT.
