概要
説明
The ISL85005ADEMO1Z platform allows for a quick demonstration of the high-performance features of the ISL85005A buck regulator.
The ISL85005A is a 4.5V to 18V input, 5A synchronous buck regulator for applications with an input voltage from multi-cell batteries or regulated 5V and 12V power rails. This device also provides an integrated bootstrap diode for the high-side gate driver to reduce the external parts count.
The ISL850xx sync buck regulators support input voltages of 3.8V to 18V and a wide output current range, offering designers a complete portfolio of devices with high efficiency and reliable performance.

12V Synchronous Buck Regulator Family
Today I would like to introduce one of the most efficient and compact synchronous buck regulator families in the marketplace today.
There are many 12V rails in industrial applications today that need a buck converter to step the voltage down to a lower voltage and deliver up to 14A. Some of these applications often require a very efficient and compact solution. The highly integrated buck regulators listed here allow the users to meet all these requirements.
The ISL85009, ISL85012 and ISL85014 are pin compatible, very efficient and are able to deliver up to 14A. In applications that need less than 5A, Renesas offers ISL85003 and ISL85005 that are pin compatible. The ISL85009, ISL85012 and ISL85014 can operate from 3.8V to 18V input voltage, and the output voltage can be set as low as 0.6V. This family is highly integrated. The high-side and low-side FETs, with a bootstrap diode and compensation circuits are all integrated which helps to reduce the size, cost and bill of material.
This family is also highly reliable. It has high-side and low-side overcurrent protection, input and output overvoltage protection, over-temperature protection and negative current protection all integrated in the IC. This family also provides full feature sets and design flexibility to customers.
For instance, the selectable OCP scheme feature gives flexibility to the power supply designer to choose between hiccup and latch-off OCP mode, depending on their application requirements. Finally, the ISL85009, ISL85012 and ISL85014 are pin compatible, highly efficient and capable of delivering up to 14A in a very small 3.5mm x 3.5mm TQFN package.
As you see in the efficiency curve here, the ISL85009 provides one of the most efficient solution in the marketplace today. To support our customers with this family, we have developed several evaluation and demo boards.
Supporting tools such as iSim model, PowerCompass, schematic and Gerber files are all available online for this family on our website.
