... For a more detailed description of the ISL6521 functionality, refer to the ISL6521 Data Sheet [1]. The ISL6521EVAL1 Reference Design The ISL6521EVAL1 evaluation board is intended to provide a versatile platform for evaluation of surface mount and thru hole components. The evaluation board is designed to meet the output voltage and current specifications shown in Table 1. The synchronous buck converter can sustain 5A of continuous load current and handle 5A step, 2.5A/µ ...

... Power Supply Indicator FIGURE 2. EXTERNAL POWER SUPPLY AND LOAD CONNECTIONS ISL6521EVAL1 Performance Enabling the Controller Once the bias voltage applied to the PWM controller reaches the rising Power-On Reset (POR) threshold, the ISL6521 initiates a soft-start interval. The point at which the ISL6521 reaches the rising POR threshold is indicated as Soft-start Begins in Figure 3 ...

... Shutdown on any one output does not shutdown all outputs. Transient Response FPGA transient specifications vary depending on overall gate usage. The ISL6521EVAL1 is designed to meet a load step of 5A with a slew rate of 2.5A/µs. During a transient, the FPGA core voltage (VOUT1) must not exceed ±50mV of +1 ...
