Datasheet  
ISL85415  
Wide VIN 500mA Synchronous Buck Regulator  
The ISL85415 is a 500mA synchronous buck  
regulator with an input range of 3V to 36V. The device  
provides an easy-to-use high-efficiency, low  
BOM-count solution for a variety of applications.  
Features  
• Wide input voltage range 3V to 36V  
• Synchronous operation for high efficiency  
• No compensation required  
The ISL85415 integrates both high-side and low-side  
NMOS FET's and features a PFM mode for improved  
efficiency at light loads. The feature can be disabled if  
forced PWM mode is desired. The device switches at  
a default frequency of 500kHz, but can also be  
programmed using an external resistor from 300kHz  
to 2MHz. The ISL85415 has the ability to use internal  
or external compensation. By integrating both NMOS  
devices and providing internal configuration options,  
minimal external components are required, reducing  
both the 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 (500kHz) or adjustable switching  
frequency 300kHz to 2MHz  
• Continuous output current up to 500mA  
• Internal or external soft-start  
• Minimal external components required  
• Power-good and enable functions available.  
With the wide V range and reduced BOM the part  
IN  
Applications  
provides an easy to implement design solution for a  
variety of applications while giving superior  
performance. It provides a very robust design for  
high-voltage Industrial applications and delivers an  
efficient solution for battery powered applications.  
• Industrial control  
• Medical devices  
• Portable instrumentation  
• Distributed power supplies  
• Cloud infrastructure  
The ISL85415 is available in a small Pb-free  
4mmx3mm DFN plastic package with an operation  
temperature range of -40°C to +125°C.
