Rad Hard and SEE Hard 12A Synchronous Buck  
Regulator with Multi-Phase Current Sharing  
ISL70002SEH  
Features  
The ISL70002SEH 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  
• DLA SMD#5962-12202  
• 12A Output Current for a Single Device (at T = +150°C)  
J
• 19A Output Current for Two Paralleled Devices  
• 1MHz or 500kHz Switching Frequency  
• 3V to 5.5V Supply Voltage Range  
12A for T ≤ +150°C. Two ISL70002SEH devices configured to  
current share can provide 19A total output current, assuming  
±27% worst-case current share accuracy.  
J
• ±1% Ref. Voltage (Line, Load, Temp. & Rad.)  
• Pre-Biased Load Compatible  
• Redundancy/Junction Isolation: Exceptional SET Performance  
• Excellent Transient Response  
The ISL70002SEH utilizes peak current-mode control with  
integrated error amp compensation and pin selectable slope  
compensation. Switching frequency is also pin selectable to  
either 1MHz or 500kHz. Two ISL70002SEH devices can be  
synchronized 180° out-of-phase to reduce input RMS ripple  
current.  
• High Efficiency > 90%  
• Two ISL70002SEH Synchronization, Inverted-Phase  
• Comparator Input for Enable and Power-Good  
• Adjustable Analog Soft-Start  
High integration makes the ISL70002SEH 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.  
• Input Undervoltage, Output Undervoltage and Adjustable  
Output Overcurrent Protection  
• QML Qualified per MIL-PRF-38535  
• Full Mil-Temp Range Operation (-55°C to +125°C)  
• Radiation Environment  
Applications  
• FPGA, CPLD, DSP, CPU Core and I/O Voltages
