TEST EQUIPMENT LIST ISL8204MEVAL1Z, ISL8206MEVAL1Z evaluation boards. EQUIPMENT PART NUMBER Since the modules are a pin for pin drop in with all necessary unique circuitry integrated in the module, the An adjustable DC Power Supply 30V, 15A, GW GPC3060D only difference in the BOM is the ISL8201M, ISL8206M, with current limit or ISL8204M POL modules. We will refer to a generic An electronic load, capable of sinking 20A Chroma 63030/63010 eval board, ISL820xMEVAL1Z to cover all three power modules. Four channel oscilloscope and probes Tektronix TDS3014 Tektronix P3010 The ISL820xMEVAL1Z POL module evaluation board is shown in Figure 1. The user can use it to evaluate the High Precision Digital Voltage Meter ESCORT 3136A performance of the Intersil ISL8201M, ISL8206M, or High Precision Digital Current Meter ESCORT 3136A ISL8204M POL modules. This board consists of power and load connectors for source and load side, switches Recommended Operating Specification for PVCC bias selection and On/Off option, and other passive components. The recommended operating specification for input/output and PVCC bias range is shown as Table 2. The input voltage range is from 1V to 20V, and the output voltage range is from 0.6V to 5V 5V for the TABLE 2. RECOMMENDED OPERATING SPECIFICATIONS ISL8201M or 0.6V to 6V for the ISL8204M and TEST ISL8206M. Additional PVCC bias source is not required PARAMETER CONDITIONS MIN TYP MAX UNIT when using an input voltage of 5V or 12V. It can connect to the input side directly. However, in wider Input Voltage 1- 20 V input ranges, which are above 14V or below 5V, the Range (V ) IN PVCC bias needs to add an external source, which Supply Voltage Fixed +5V 4.5 5.0 5.5 V provides operation bias of the module. The output Range (PVCC) Supply voltage is initially set at 1.5V for typical evaluation. The Fixed +12V 9.6 12.0 14.4 V user can easily set the output voltage by changing the Supply (refer to Figure 8). value of R 1 Wide Range 6.5 - 14.4 V Supply Output Voltage ISL8201M 0.6 - 5 V Range (V ) OUT ISL8204M and 0.6 - 6 V ISL8206M Current Setting for R1 = 6.49k -1.5 - V V OUT Output Current ISL8201M - - 10 A (Load Current) ISL8206M - - 6 A ISL8204M - - 4 A Current Limit ISL8201M -17 - A (PVCC = 12V) R = 3.57k SEN-IN ISL8206M -8.8 - A R = 4.12k SEN-IN ISL8204M -6.6 - A R = 2.87k SEN-IN Table 3 lists the typical applications various output voltages and its corresponding resistance.
