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
• 14A output current for a single device (at T = +125°C)  
J
• 19A output current for two paralleled devices  
• Available in a thermally enhanced heatsink package - R64.C  
• 1MHz or 500kHz switching frequency  
• 3V to 5.5V supply voltage range  
12A for T ≤ +150°C. The two ISL70002SEH devices configured  
J
to current share can provide 19A total output current, assuming  
±27% worst-case current share accuracy.  
• ±1% Ref. voltage (line, load, temp. & rad)  
• Pre-biased load compatible  
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 devices can be synchronized 180°  
out-of-phase to reduce input RMS ripple current.  
• Redundancy/junction isolation: Exceptional SET performance  
• Excellent transient response  
• High efficiency > 90%  
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.  
• Two ISL70002SEH synchronization, inverted-phase  
• Comparator input for enable and power-good  
• Input undervoltage, output undervoltage and adjustable  
Output overcurrent protection  
• QML qualified per MIL-PRF-38535  
Applications  
• FPGA, CPLD, DSP, CPU Core and I/O Voltages  
• Full Mil-temp range operation (-55°C to +125°C)  
• Radiation environment  
• Low-voltage, High-density Distributed power systems
