Radiation Hardened and SEE Hardened 6A  
Synchronous Buck Regulator with Integrated  
MOSFETs  
ISL70001SRH  
Features  
• Electrically Screened to DSCC SMD 5962-09225  
The ISL70001SRH 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  
• QML Qualified per MIL-PRF-38535 Requirements  
• Full Mil-Temp Range Operation (T = -55°C to  
A
+125°C)  
• Radiation Hardness  
- Total Dose [50-300rad(Si)/s] . . . 100krad(Si) min  
capacity is 6A for T < +145°C.  
• SEE Hardness

The ISL70001SRH utilizes peak current-mode control  
with integrated compensation and switches at a fixed  
frequency of 1MHz. Two ISL70001SRH devices can be  
synchronized 180° out-of-phase to reduce input RMS  
ripple current. These attributes reduce the number and  
size of external components required, while providing  
excellent output transient response. The internal  
synchronous power switches are optimized for high  
efficiency and good thermal performance.

• High Efficiency > 90%  
• Fixed 1MHz Operating Frequency  
• Operates from 3V to 5.5V Supply  
• ±1% Reference Voltage over Line, Load,  
Temperature and Radiation  
The chip features a comparator type enable input that  
provides flexibility. It can be used for simple digital  
on/off control or, alternately, can provide  
• Adjustable Output Voltage  
undervoltage lockout capability by precisely sensing  
the level of an external supply voltage using two  
external resistors. A power-good signal indicates  
when the output voltage is within ±11% typical of the  
nominal output voltage.

• Excellent Dynamic Response  
• Bi-directional SYNC Pin Allows Two Devices to be  
Synchronized 180° Out-of-Phase  
Regulator start-up is controlled by an analog soft-start  
circuit, which can be adjusted from approximately 2ms  
to 200ms using an external capacitor.  
• Device Enable with Comparator Type Input  
• Power-Good Output Voltage Monitor  
• Adjustable Analog Soft-Start  
The ISL70001SRH 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  
• Starts Into Pre-Biased Load  
High integration makes the ISL70001SRH 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.  
Applications*(see page 16)  
• FPGA, CPLD, DSP, CPU Core or I/O Voltages  
• Low-Voltage, High-Density Distributed Power  
Systems  
Specifications for Rad Hard QML devices are  
controlled by the Defense Supply Center in  
Columbus (DSCC). The SMD numbers listed in the  
Ordering Information Table on page 2 must be  
used when ordering.

devices are contained in SMD 5962-09225. A link
