The ISL70002SEHEVAL3Z evaluation board is
designed to demonstrate the features of the
ISL70002SEH, a TID and SEE hardened 22A
synchronous buck regulator IC with integrated
MOSFETs intended for space applications. For more
detailed information about the ISL70002SEH, refer to
the ISL70002SEH Datasheet.
The ISL70002SEHEVAL3Z is similar to the
ISL70002SEHEVAL1Z, but AGND is separated from
PGND. This allows remote ground sensing to
compensate for voltage loss in the ground path.
Ground sensing is an important feature when
providing a tightly regulated core voltage for a FPGA
or microcontroller.
Features
▪Separate VOUT and GND Force and Sense
terminals
▪Optional 2x2mΩemulated trace resistance
included on board
▪3V to 5.5V input
▪Adjustable VOUT from 0.6V to 0.85×VIN
Recommended Equipment
▪A 6V power supply capable of at least 10A
▪An electronic load capable of sinking at least 12A
▪Three Digital Multimeters (DMMs)
▪A 500MHz four-channel oscilloscope
▪Optional: One differential voltage probe to measure
one signal with respect to a different ground.

1. Functional Description
1.1 Quick Start Instructions
1. Toggle S1 to the down (OFF) position.
2. Study Figure 2 to see how to hook up the evaluation board.
3. Turn on the power supply. Set the output voltage to 5V and set the output current limit to 10A. Turn off the power
supply output.
4. Connect the positive lead of the power supply to J1 and the negative lead of the power supply to J2.
5. Turn on the electronic load and set the output current to 5A.
6. Connect the positive lead of the electronic load to VOUT (J39) and to VOUT_SNS with two separate wires.
7. Connect the negative lead of the electronic load to GND (J40) and to GND_SNS with two separate wires.
8. (Optional) Configure one DMM to monitor the input voltage from TP7 to TP11.
9. Configure another DMM to monitor the output voltage from TP13 to TP11 or the VOUT and GND terminals.
10. Configure a third DMM to monitor the voltage on the electronic load.
11. Connect Channel 1 of the oscilloscope to J6 (or from TP33 to TP28) to monitor the rectangular waveform on
the LXx pins.
12. Connect Channel 2 of the oscilloscope to J14 (or from TP36 to TP37) to monitor the output voltage. Ripple
voltage is customarily measured AC-coupled with 20MHz bandwidth limiting.
13. Toggle S1 to the up (ON) position.
14. Verify the output voltage is 1.0V ±3% and the frequency of the LXx waveform is 1MHz ±10%.
15. Vary the load and observe VOUT at the load maintaining regulation. The voltage at the VOUT-GND terminals
should boost under increasing load to account for the resistance of the wires to the load.
16. To see more pronounced compensation, insert some intentional resistance (1-10mΩ) between the VOUT
and/or GND (force) terminals and the load. Follow the Onboard Resistor Instructions to use the onboard 2mΩ
resistors.

1.2 Onboard Resistor Instructions
1. The configuration shown in Figure 3 uses onboard series resistors to emulate resistive loss in a PCB or IC
package.
2. Install VSNS_LOAD and GSNS_LOAD jumpers.
3. Connect the DC load to the LOAD_VOUT and LOAD_GND terminals. Solder, clip, or bolt wires to the terminals.
4. Connect one voltmeter to the VOUT and GND terminals. Connect another to the VOUT_SNS and GND_SNS
terminals as shown in Figure 3.
5. Enable, disable, and modulate the DC load to observe the POL converter compensating for the trace
impedance. This includes 4mΩof onboard chip resistors and parasitic resistance of the evaluation PCB.
Observations should be similar to Figure 19.

2.1 Layout Guidelines
PCB design files are available on the ISL70002SEHEVAL3Z webpage for you to study or incorporate into your
design.
1. Use a six-layer PCB with 2 ounce (70µm) copper outer layers or an equivalent in more layers.
2. Two interior layers should be dedicated for PGND planes. In addition, place a square island of PGND on the
top layer directly underneath the body of the ISL70002SEH. Fill this area with vias to connect the top island to
the PGND planes for optimal electrical and thermal performance. The ISL70002SEHVFE parts have an
exposed metal bottom that can be soldered to the PCB. You may also use a thermal interface material such as
a Sil-Pad to ensure good thermal contact between the PCB and the IC, with or without an exposed metal
bottom.
3. Top and bottom layers should be used primarily for high-power traces ensuring the lowest impedance paths
between the input capacitors, the IC, the inductor, and the output capacitors. Where convenient, use the top
layer to connect the IC pins to the various small signal resistor and capacitors.
4. Connect all DGND and PGNDx pins to the PGND island under the part. Connect all PVINx pins to the input
power supply using the lowest resistance PCB layers (typically the top and bottom) if possible.
5. Locate a PVIN ceramic bypass capacitor as close as possible to each pair of PGNDx and PVINx pins on the
top of the PCB and connect them to the pins in the top layer.
6. Group the small signal components together near their pin(s) on U1. This should include the components that
touch pins 1-16 and 59-63.
7. Locate the output voltage resistive divider as close as possible to the FB pin of the IC. Run a VOUT sense route
from the top node of the divider directly to the positive terminal on the load. This route can be on any layer.
8. Enclose the small signal components in an AGND pour, and duplicate that pour on an interior layer. Connect
these together with multiple vias. Connect the AGND pin and passive component leads of the IC to this pour.
9. Connect the GND side of the VOUT capacitors to the PGND planes with a low impedance path back to the IC.
10. Run an AGND route from the copper pour all the way to the negative terminal of the load. Run this parallel to
the VOUT sense route that connects the FB divider to the load.
11. Use a small island of copper to connect the LXx pins of U1 to the inductor(s), L1 (and L2, if using two parallel
inductors), to minimize the routing capacitance that degrades efficiency. Separate the island from ground and
power planes as much as possible. This copper pattern may need to be replicated on multiple layers to reduce
the resistance.
12. Keep all signal traces as short as possible.
13. A small series snubber (R25 and C20) connected from the LXx pins to the PGNDx pins can be used to dampen
ringing on the LXx pins if desired.
14. For optimum thermal performance, place a pattern of vias on the top layer of the PCB directly underneath U1.
Connect the vias to the ground planes, which serve as a heatsink.
