ISL8023, ISL8024
PCB Layout Recommendation
The PCB layout is a very important converter design step to make
sure the designed converter works well. For ISL8023, ISL8024,
the power loop is composed of the output inductor L’s, the output
capacitor C OUT , the PHASE’s pins, and the PGND pin. It is
necessary to make the power loop as small as possible and the
connecting traces among them should be direct, short and wide.
The switching node of the converter, the PHASE pins, and the
traces connected to the node are very noisy, so keep the voltage
feedback trace away from these noisy traces. The input capacitor
should be placed as close as possible to the VIN pin. The ground
of input and output capacitors should be connected as closely as
possible. The heat of the IC is mainly dissipated through the
thermal pad. Maximizing the copper area connected to the
thermal pad is preferable. In addition, a solid ground plane is
helpful for better EMI performance. It is recommended to add at
least 5 vias ground connection within the pad for the best
thermal relief.

CHANGE
Electrical spec table: “OUTPUT REGULATION” on page 6, under VFB Bias Current section, changed the typical
value from 0.1μA to 0.01μA.
Added ISL8023EVAL3Z, ISL8024EVAL3Z and ISL8023AEVAL3Z, ISL8024AEVAL3Z Evaluation Boards to
Page 2: Updated with new silkscreen to show the correct placement of U1-Pin1.
Page 3: Pin Descriptions , COMP, FB Changed the description from "Must connect COMP to SGND in internal
compensation mode " to "Recommend connect COMP to SGND in internal compensation mode".
Updated Figure 2 to show the COMP pin tied to GND
Page 18: Put compensator zero ω cz2 = (5to8) R0C0" changed to "..... R2C3"
Figure 43, Simulated Loop Gain: Added Y-axis title to the top graph: GAIN (VLOOP(S(fi)))
In the “Absolute Maximum Ratings” on page 6, changed “VIN” from “-0.3V” to “-0.3V to 6.5V (DC) or 7V (20ms)"
Revised description, Features and Applications on page 1. Added Figure 2.
Initial Release.
