Datasheet  
ISL73006SLH  
Radiation Hardened 18V, 1A Point-of-Load Regulator  
The ISL73006SLH is a radiation hardened  
Point-of-Load (POL) buck regulator that provides up  
to 1A of output current capability with an input voltage  
ranging from 3V to 18V. The device uses constant  
frequency peak current mode control architecture for  
fast loop transient response. The device uses internal  
compensation or an external Type-II compensation to  
optimize performance and stabilize the loop. The  
ISL73006SLH has a default switching frequency of  
500kHz.  
Features  
Qualified to Renesas Rad Hard QML-V Equivalent  
Screening and QCI Flow (R34TB0001EU)  
• All screening and QCI is in accordance with  
MIL-PRF-38535 Class-V  
Input Bias Voltage  
• 3V to 18V  
Internal or external loop compensation  
1% reference voltage over-temperature and  
The ISL73006SLH integrates high-side (P-channel)  
and low-side (N-channel) power FETs. There are  
options for external or internal compensation and  
slope control that can be implemented with a  
minimum of external components reducing the BOM  
count and design complexity.
