Rad Hard and SEE Hard 6A Synchronous Buck Regulator  
ISL70001ASEH  
Features  
The ISL70001ASEH 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
• 50% Lower Shutdown Supply Current than the ISL70001SEH  
• Available in a thermally enhanced heatsink package - R48.B  
• Highly Efficient: 94% Peak Efficiency  
for T < +145°C.  
J
The ISL70001ASEH utilizes peak current-mode control for  
excellent output load transient response and features integrated  
compensation and switches at a fixed frequency of 1MHz to  
reduce component size and count. In application where two POLs  
are needed, two ISL70001ASEH devices can be synchronized  
180° out-of-phase to reduce the overall input RMS ripple current.  
The internal synchronous power switches are optimized for high  
efficiency and good thermal performance.  
• Operates from 3V to 5.5V Supply  
• Adjustable Output Voltage

IN  
• Bi-directional SYNC Pin Allows Two Devices to be Synchronized  
180° Out-of-Phase  
• Power-Good Output Voltage Monitor  
• Adjustable Analog Soft-Start  
The ISL70001ASEH incorporates fault protection for the  
regulator. The protection circuits include input undervoltage,  
output undervoltage, and output overcurrent.  
• Input Undervoltage, Output Undervoltage and Output  
Overcurrent Protection  
High integration and class leading radiation tolerance makes  
the ISL70001ASEH 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.  
• Electrically Screened to DLA SMD 5962-09225  
• QML Qualified per MIL-PRF-38535 Requirements
