Connect the positive and n egative terminals of the load to the VOUT and GND pins, respectively. Be aware that electronic loads represent a negative impedance to the regulator and if set to a too high current will trigger Hiccup mode. 2. Preset the power supply output to between 4 and 36V, and then turn it off. If longer cables are used between the source and the EVB (>0.5m total), a damping capacitor should be installed at the input terminals. Especially when Vin is ≥ 24V. 3. Connect the positive and negative terminals of the power supply output to the VIN and GND pins, respectively. 4. Turn the power supply on. The MP/MPQ4415MGQB will automatically startup. 5. To use the Enable function, apply a digital input to the EN/Sync pin. Drive EN higher than 1.45V to turn on the regulator, drive EN less than 1V to turn it off. 6. To use the Sync function, apply a 450kHz to 2 .2MHz external clock to the EN/ Sync pin to synchronize the internal clock rising edge. 7. The output voltage is set by the external resistor divider. The feedback resistor (R FB1) also sets the feedback loop bandwidth with the internal compensation capacitor. Choose RFB1 to be around 40kΩ when VOUT  1V. RFB2 can then be calculated with below equation: 10.807V V RR OUT FB1 FB2 8. The T-type network is highly recommended when VOUT is low. 9. RT + RFB1 is used to se t the loop bandwidth. The lower RT +RFB1 is, the higher the bandwidth. However, a high bandwidth may cause an insufficient phase margin, resulting in loop unstable. Therefore, a proper RT value is required to make a trade -off between bandwidth and phase margin. Below table lists the recommended feedback resistor and R T values for common output voltages.
