Rad Hard and SEE Hard 6A Synchronous Buck Regulator  
ISL70001SEH  
Features  
The ISL70001SEH is a radiation hardened and SEE hardened  
high efficiency monolithic synchronous buck regulator 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 capacity is 6A  
• ±1% Reference Voltage Over Line, Load, Temperature and  
Radiation  
• Current Mode Control for Excellent Dynamic Response  
• Full Mil-Temp Range Operation (T = -55°C to +125°C)  
A
• High Efficiency > 90%  
for T < +145°C.  
J
• Fixed 1MHz Operating Frequency  
• Operates from 3V to 5.5V Supply  
• Adjustable Output Voltage  
High integration and class leading radiation tolerance makes  
the ISL70001SEH an ideal choice to power many of today’s  
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.  
• Device Enable with Comparator Type Input  
• Power-Good Output Voltage Monitor  
• Adjustable Analog Soft-Start  
Applications  
• FPGA, CPLD, DSP, CPU Core or I/O Voltages  
• Low-Voltage, High-Density Distributed Power Systems  
• Input Undervoltage, Output Undervoltage and Output  
Overcurrent Protection
