Positive Logic: Floating = Enabled Negative Logic: Floating = Disabled Must be connected to Vo(-) See ‘Trim Feature’ below Must be connected to Vo(+) Remote Sense The remote sense regulates the output voltage across the sensing connections, and should be connected at the point on the board where regulation is desired. It is used to compensate for contact and distribution losses to the load. Efforts should be made to minimize these losses to help reduce noise and improve efficiency of the system.

This is achieved by connecting a resistor between Trim and Sense(+) pins: The Trim-down configuration is used to reduce the level of the nominal output voltage. Trim-down is achieved by connecting a resistor between Trim and Sense(-) pins: Vo(+) Vo(+) Sense(+) Sense(+) Rtrim_up Trim Cload Trim Iload Sense(-) Sense(-) Vo(-) Cload Rtrim_down Vo(-) Figure 3 Figure 4 The value of the trim-up resistor is determined by the following equation: The value of the trim-down resistor is determined by the following equation: QHS12-120 Trim-up and Trim-down Resistance Resistance (kOhms) 10000 The voltage between the Vo(+) and Vo(-) terminals must not exceed the minimum output over voltage shut-down value indicated in Table 3. This limit includes any increase in voltage due to remote-sense compensation and output voltage set-point adjustment (trim). Rup Rdow n 1000 The amount of power delivered by the module is defined as the voltage at the output terminals multiplied by the output current. (Output Voltage Set Point, typ x Output Current, Max) When using remote sense and/or trim, the output voltage of the module can be increased, and may result in an increase of output power. Care should be taken to ensure that the maximum output power of the module remains at or below the maximum rated power. 100 10 0 Figure 5 2 4 Delta (%) 6 8 10 www.murata-ps.com/support 6 QHS12-6201001509_D01_21/04/08 Iload Q-Class Converters Murata Power Solutions QHS12-120 Model Efficiency Curves Efficiency at 25 Degrees C Figure 6 QHS12-120 Efficiency Test Setup Input Reflected Ripple Input Reflected Ripple Test Circuit is ic Vin Vi(+) 12uH 220uF, ESR<0.1 ohms @ 100kHz 33uF, ESR<0.7 ohms @ 100kHz RTN DC-DC Converter Vi(-) Figure 8 Input Current at full load, 48Vdc input. 5 mA/div, 500 uS /div.
