QUICK START GUIDE (ADJUSTABLE OUTPUT) The output voltage of this board is set externally which ranges from 0.8V to 5V by operating from +2.5V to +5.5V input as the figure 4. The default output voltage of this board is set to 1.1V. The board layout accommodates most commonly used resistors and capacitors. 1. Attach the positive and negative ends of the load to the VOUT and GND pins, respectively. 2. Attach the Input Voltage (2.5V ≤ VIN ≤ 5.5V) and Input Ground to the VIN and GND pins respectively. 3. To enable the MPQ20051, apply a voltage 1.5V ≤ V EN ≤ 5.5V, to the EN pin. To disable the MPQ20051, apply a voltage, V EN < 0.4V, to the EN pin. The EN pin can be connected to V IN with a 100kΩ resistor for automatic startup. 4. The Output Voltage V OUT can be changed by varying R1. Calculate the new value by formula: OUT FB VR1 R2( 1)V= − Where VFB = 0.8V and R2 = 10kΩ. Example: For V OUT = 1.1V: 1.1R1 10k Ω 1 3.75k Ω0.8 Therefore, use a 3.74kΩ standard 1% value. Figure 4
