General Description

This app note covers the ISL8201MEVAL1Z, 
ISL8204MEVAL1Z,  ISL8206MEVAL1Z evaluation boards.  
Since the modules are a pin for pin drop in with all 
necessary unique circuitry integrated in the module, the 
only difference in the BOM is the ISL8201M, ISL8206M, 
or ISL8204M POL modules.  We will refer to a generic 
eval board, ISL820xMEVAL1Z to cover all three power 
modules.

The ISL820xMEVAL1Z POL module evaluation board is 
shown in Figure 1. The user can use it to evaluate the 
performance of the Intersil ISL8201M, ISL8206M, or 
ISL8204M POL modules. This board consists of power 
and load connectors for source and load side, switches 
for PVCC bias selection and On/Off option, and other 
passive components.

The input voltage range is from 1V to 20V, and the 
output voltage range is from 0.6V to 5V 5V for the 
ISL8201M or 0.6V to 6V for the ISL8204M and 
ISL8206M. Additional PVCC bias source is not required 
when using an input voltage of 5V or 12V. It can 
connect to the input side directly. However, in wider 
input ranges, which are above 14V or below 5V, the 
PVCC bias needs to add an external source, which 
provides operation bias of the module. The output 
voltage is initially set at 1.5V for typical evaluation. The 
user can easily set the output voltage by changing the 
value of R

 (refer to Figure 8).

Installation

Recommended Operating Specification

The recommended operating specification for 
input/output and PVCC bias range is shown as Table 2.

Table 3 lists the typical application’s various output 
voltages and its corresponding resistance.
