Efficiency Typical: 84% (at 28VDC output, nominal input, full load, room temperature) EMC Designed to meet MIL-STD-461F* CE101, CE102, CS101, CS114, CS115, CS116, RE101, RE102, RS101, RS103 Ripple and Noise Less than 100 mVp-p, typical (max. 1%) without external capacitance. When connected to system capacitance ripple drops significantly. Transient Over-and-undershoot Output change at load transient of 10 to 100% with Tr & Tf of max 30 μs is less than 5% of output voltage. Output recovers to steady stated within less 0.1 ms, typically. Turn on Transient No overshoot. * Compliance achieved with 5μH LISN, shielded harness and static resistive load.

To turn the power supply OFF, apply a TTL “0” signal or SHORT to SIGNAL RTN. To turn the power supply ON, apply a TTL “1” signal or leave this pin OPEN. If not used (always ON), leave this pin OPEN. This signal is referenced to SIGNAL RTN. SYNC IN 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. This signal is referenced to SIGNAL RTN. SYNC OUT The SYNC OUT signal can be used to synchronize the system to the power supply's clock. This signal is referenced to SIGNAL RTN. SIGNAL RTN The SIGNAL RTN is referenced to IN RETURN. This is used as grounding for SYNC IN, INHIBIT and SYN OUT signals. 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). For output voltage above 8V, the use of remote sense has a max limit of 0.25V voltage dropout between converter’s output and load terminals. For output voltage below 8V, the use of remote sense has a max limit of 0.5V voltage dropout between converter’s output and load terminals. When not used connect SENSE to OUT and SENSE RTN to OUT RTN. CURRENT SHARE (Pin #7) The CURRENT SHARE signal is used to connect the power supply in parallel to other power supplies and have them divide equally the power between one another. Connect all CURRENT SHARE signals of all paralleled power supplies together. This signal is referenced to SENSE RTN (pin #8). POWER GOOD (Pin #9) The VOLTS GOOD TTL signal is used to indicate if the output voltage is within the calibrated tolerances (typical 5%). TTL “1”- output is within the required tolerances. TTL “0” - output is not within the required tolerances. This signal is referenced to SENSE RTN (pin #8).
