DATASHEET  
ISL70002SEH, ISL73002SEH  
Radiation Hardened and SEE Hardened 22A Synchronous Buck Regulators with  
Current Sharing  
FN8264  
Rev.12.01  
Mar 31, 2022  
The ISL70002SEH and ISL73002SEH (ISL7x002SEH) are  
Features  
radiation hardened and SEE hardened high-efficiency  
• DLA SMD 5962-12202  
• Maximum output current (“Single Phase”):  
- 22A with external Schottky (T ≤125°C, PVIN ≤5.5V)  
monolithic, synchronous buck regulators with integrated  
MOSFETs. This single chip power solution operates over an  
input voltage range of 3V to 5.5V and provides a tightly  
regulated output voltage that is externally adjustable from  
0.8V to ~85% of the input voltage. Output load current  
capability is primarily determined by PVIN voltage with up to  
J
- 18A (T ≤125°C, PVIN ≤5.5V)  
J
- 14A (T ≤125°C, PVIN ≤6.2V)  
J
- 12A (T ≤150°C, PVIN ≤6.2V)  
22A for a single IC at PVIN ≤ 5.5V for T ≤ +125°C. Two  
J
J
ISL7x002SEH devices, configured to current share, can  
• Maximum output current (“Dual Phase”)  
- 38A (27% worst case current sharing)  
• 1MHz or 500kHz switching frequency  
provide up to 38A of total output current at PVIN ≤ 5.5V for T  
≤ +125°C assuming ±27% worst-case current share  
accuracy.  
J
• 3V to 6.2V supply voltage range  
The devices use peak current-mode control with integrated  
error amp compensation and pin-selectable slope  
• ±1% reference voltage (line, load, temperature, and rad)  
compensation. Switching frequency is also pin selectable to  
either 1MHz or 500kHz. Two devices can be synchronized  
180° out-of-phase to reduce input RMS ripple current.  
• Redundancy/junction isolation: exceptional SET  
performance  
• Excellent transient response  
High integration makes them an ideal choice to power small  
form factor applications. Two devices can be synchronized to  
provide a complete power solution for large scale digital ICs,  
like Field Programmable Gate Arrays (FPGAs) that require  
separate core and I/O voltages.  
• High efficiency >90%  
• Two ISL7x002SEH synchronization, inverted-phase  
• Comparator input for enable and power-good  
• Input undervoltage, output undervoltage, and adjustable  
output overcurrent protection  
The ISL7x002SEH is available in a thermally enhanced heat  
spreader package (R64.C)  
• QML qualified per MIL-PRF-38535  
• Full military temperature range operation (-55°C to  
+125°C)  
Applications  
• FPGA, CPLD, DSP, CPU core, and I/O voltages  
• Radiation environment - ISL70002SEH  
- HDR (50-300rad(Si)/s): 100krad(Si)  
- LDR (0.01rad(Si)/s): 50krad(Si)  
• Low-voltage, high-density distributed power systems  
• Radiation environment - ISL73002SEH  
- LDR (0.01rad(Si)/s): 50krad(Si).  
• SEE hardness (See the SEE Test report for details)
