DATASHEET  
ISL85410  
Wide V 1A Synchronous Buck Regulator  
IN  
FN8375  
Rev.8.00  
Mar 15, 2019  
The ISL85410 is a 1A synchronous buck regulator with an  
input range of 3V to 40V. It provides an easy-to-use, high  
efficiency low BOM count solution for a variety of applications.  
Features  
• Wide input voltage range: 3V to 40V  
• Synchronous operation for high efficiency  
• No compensation required  
The ISL85410 integrates both high-side and low-side NMOS  
FETs and features a PFM mode for improved efficiency at light  
loads. This feature can be disabled if a forced PWM mode is  
needed. The ISL85410 switches at a default frequency of  
500kHz; however, it can also be programmed using an  
external resistor from 300kHz to 2MHz. The ISL85410 has the  
ability to use internal or external compensation. By integrating  
both NMOS devices and providing internal configuration  
options, minimal external components are required, which  
reduces BOM count and complexity of design.  
• Integrated high-side and low-side NMOS devices  
• Selectable PFM or forced PWM mode at light loads  
• Internal fixed frequency (500kHz) or adjustable switching  
frequency (300kHz to 2MHz)  
• Continuous output current up to 1A  
• Internal or external soft-start  
• Minimal external components required  
• Power-good and enable functions available  
With a wide V range and reduced BOM, the ISL85410  
IN  
provides an easy to implement design solution for a variety of  
applications while giving superior performance. The ISL85410  
provides a very robust design for high-voltage industrial  
applications and an efficient solution for battery powered  
applications.  
Applications  
• Industrial control  
• Medical devices  
The ISL85410 is available in a small Pb-free 4mmx3mm DFN  
plastic package with a full-range industrial temperature of  
-40°C to +125°C.  
• Portable instrumentation  
• Distributed power supplies  
• Cloud infrastructure
