... Layout plots and part lists are provided at the end of the application note for this design. Quick Start Evaluation The ISL6310EVAL1Z is designed for quick evaluation after following only a few simple steps. All that is required is two bench power supplies, Oscilloscope and Load. To begin evaluating the ISL6310EVAL1Z follow the steps below ...

... J2) and GND terminal (J3, J4). OUT 6. Move the “Enable” switch (S1) to the OFF position releasing the IC ENLL pin to rise to begin regulation. After step 6, the ISL6310EVAL1Z should be regulating the output voltage, at the “V +” and “V OUT P21) and J5 to the REF voltage. The “PGOOD Indicator” ...

... OPEN FIGURE 2. LOAD TRANSIENT GENERATOR Inductor DCR Static Current Sense Points A unique feature of the ISL6310EVAL1Z is the ability to measure the voltage drop across the DCR of each channel’s inductor by multimeter. This is accomplished with the use of a capacitor and resistor series circuit which is placed in parallel across each inductor as illustrated in Figure 3 ...

... All that is required is a single resistor between the OFS and VCC pins, or the OFS pin and GND. The ISL6310EVAL1Z has both of these resistor options available on the board. To positively offset the output voltage populate resistor R5. To negatively offset the output voltage populate resistor R7 ...

... ISL6310 Performance Soft-Start Interval The typical start-up waveforms for the ISL6310EVAL1Z are shown in Figure 5. The waveforms represented in this image show the soft-start sequence of the regulator DAC set to 1.50V. Before the soft-start interval begins, VCC and PVCC are above POR and the DAC is set to 11. With these two ...

ISL6310EVAL1Z PRE-POR OVERVOLTAGE PROTECTION Efficiency The efficiency of the ISL6310EVAL1Z board, loaded from 0A to 60A, at both PVCC = 5V and 12V are plotted in Figure 14 for V = 1.5V. Measurements were performed at room OUT temperature and taken at thermal equilibrium without any air flow. The efficiency peaks just below 88% at 35A for the ...

... Down-Converting From a Different Input Voltage The ISL6310EVAL1Z is powered from bench supplies, the input labeled ‘+12V’ can be adjusted down as desired. If experimenting with a lower voltage, be mindful of a few aspects: • The duty cycle of the controller is limited to 66%; the circuit will not be capable of properly regulating the output ...
