To enable this feature, connect the +Sense and -Sense pins to the +Vout and -Vout pins, respectively, at the point in the circuit where the tightest regulation is required (Figure 1). The sense leads conduct very little current compared with the power leads and therefore provide a more accurate indication of load voltage for regulation purposes. This enables the converter to increase (or decrease) its output voltage to compensate for any load distribution losses, allowing for a more precise load voltage. Refer to the product data sheet for the maximum output voltage compensation range of the sense function. + Vout + Vin + Sense ON/OFF - Vin SLC100 Trim (Top View) - Sense - Vout CB * CL Load CB * When using remote sense with dynamic loads, the transient response at the point of load may be limited by the inductance present in the power lines. Severe load steps may require the addition of a capacitor CL across the output lines. When the load demands an immediate increase in load current, this capacitor helps to supply a portion of the current and reduces the burden on the converter. When the load is physically distanced from the converter, the inductance of the power leads, and any bypass conductance at the load, can result in increased phase shift in the converter's feedback loop, causing instability. This situation can be eliminated by inserting bypass capacitors (CB) from the outputs to the sense leads directly at the output pins. These capacitors de-couple any AC on the power lines and assure that only the DC voltage is sensed. If remote sensing is not desired then +Sense and Sense must be tied to their respective outputs for proper operation. Output Voltage Trim Figure 1 - Remote Sensing Circuit In general, the line resistance, or load drop, between the output pins of the converter and load should be minimized. Using remote sense a large line resistance, with a regulated load voltage, will result in a higher output voltage at the output of the DC/DC Converter. To prevent exceeding the converter's output power limits, a higher output voltage will require a reduction in the maximum allowable output current in accordance with the voltage/current power relationship. To minimize the line resistance between the converter and the load, the converter should be placed as close to the load as possible. Line resistance can further be decreased by using heavy gauge wire or by increasing the cross sectional area of the PC board traces. The SLC100's output voltage may be adjusted high or low by an amount indicated on the product data sheet. As shown in Figure 2, to raise the converter's output voltage a resistor must be placed between the Trim pin and +Vout pin. + Vout + Vin + Sense ON/OFF - Vin SLC100 Trim (Top View) - Sense RT Load - Vout Figure 2 - Trim Up Circuit Product: www.cdpoweronline.com SLC100 3/2004 5 APPLICATION NOTES Remote ON/OFF Function Protective Functions To lower the converter output voltage a resistor must be placed between the Trim pin and -Vout pin as shown in Figure 3. + Vout + Vin + Sense ON/OFF SLC100 Trim (Top View) - Sense Load RT - Vout - Vin Figure 3 - Trim Down Circuit The resistance value required to achieve the desired amount of positive/negative trim can be determined by referring to the trim table for each model. If trimming is not desired then the Trim pin may be left open. Remote ON/OFF Control Function The SLC100 is equipped with a primary ON/OFF pin used to remotely turn the converter on or off via a system signal. The input is TTL open-collector and/or FET open-drain compatible. For the positive logic model a system logic low signal will turn the unit off. For negative logic models a system logic high signal will turn the converter off. For negative logic models where no control signal will be used the ON/OFF pin should be connected directly to -Vin to ensure proper operation. For positive logic models where no control signal will be used the ON/OFF pin should be left open. + Vout + Vin + Sense ON/OFF SLC100 (Top View) - Vin Trim - Sense - Vout Control Signal Figure 4 - Remote ON/OFF Control Circuit Product: www.cdpoweronline.com Temperature Shutdown The over temperature shutdown feature of the SLC100 will cause the unit to shutdown at a typical pwb temperature of TBD. This protective feature is comprised of a thermistor in the units control loop. At a temperature of TBD this circuit will cause the PWM to go into an idle mode, resulting in no output from the converter and preventing damage to the converter components. When the temperature of the unit drops below TBD the fault condition will clear and the converter will resume normal operation. If the cause of the over temperature condition is not identified and corrected the unit will continue to cycle on and off indefinitely. Input Under-Voltage Shutdown The nominal input voltage for the SLC100 is 48Vdc. Once turned on reducing the input voltage to 32.5 Vdc nominal will shut down the device. At an input voltage less than 32.5V the under-voltage sensing circuit will send a signal to the PWM causing it to go into idle mode. This will result in no output from the converter, protecting the unit from a high input current condition. When the input voltage returns to a level above 32.5V the unit will return to normal operation. The unit will typically turn on at an input voltage of 33.7V nominal as indicated on the Product Data Sheet. This is due to hysterisis designed into the protective circuit to prevent excessive cycling of the converter. Brick Wall Current Limiting To protect against fault or short-circuit conditions on the output, each module is equipped with current-limiting circuitry designed to provide continuous protection. After reaching the current limit point (typically 20% above the rated output current), the voltage will range between its rated value and zero, depending upon the amount of overload. The unit will remain in operation continuously during this period down to a short-circuit condition. Once the short or overload has been eliminated, the output voltage will return to normal without cycling the input power.
