The ISL6218CV is a highly integrated and specialty component for providing all the necessary dc-dc supplies, including input boost converter, power up/down sequence, adjustable output voltage and full-featured protection, for Industrial PC motherboard and server applications. The ISL6218CV is specifically designed to provide the most cost effective, compact, high performance solution for ITX and ATX form factor motherboards and servers.

The ISL6218CV is a a highly integrated, low-cost, chip-enabled, multi-output power supply IC. It includes an integrated boost converter, power up and power down sequence, adjustable output voltage, and full range of protections. The ISL6218CV is intended for use in industrial PC motherboards and server applications, where high efficiency and a low cost are required.

The key features of the ISL6218CV include a microcontroller-driven boost converter, output step-down converter, and optional auxiliary outputs, enabling a direct point of load power solution and eliminating the need for additional power supply components. In addition, the device provides over-voltage and over-current protection, as well as short-circuit protection. The ISL6218CV operating temperature range is -40°C to +85°C, and it is available in the 20-pin HTSSOP package.

The ISL6218CV is based on a voltage-mode-controlled DC-DC converter. The output voltage is adjustable with a single external resistor. The power up sequence is started with a positive going voltage on the enable pin EN. During the startup of the device, the internal timer enables the EN pin after the specified power up interval, then the PGOOD bit will change from low to high, indicating that all outputs are powered up and ready.

Once the power up sequence starts, the boost converter will increase the output voltage of the VBUS wire until it reaches the programmed output voltage.Then the output driver will supply the current to the downstream power rails.The output current of the DC-DC converter is also adjustable with a single external resistor.In addition, the device can provide an adjustable output current limit to protect the output from overload.

The ISL6218CV also provides an additional negative supply to the system, VEE.The VEE pin can be powered through the EN pin or through an external input. The device will source power to VEE rail when the voltage of VEE is less than 1V. In addition, the device will also provide system-level protection by monitoring the VBUS, VEE and PGOOD levels.

The ISL6218CV is an exceptionally useful component, offering many advantages to designs in the ITX and ATX form factors. It offers high efficiency, low cost and full-featured protection, as well as an integrated boost converter, output step-down converter and optional auxiliary outputs, allowing designers to eliminate additional supply components. The ISL6218CV is a good choice for industrial PC motherboards and servers, providing a reliable and efficient power supply solution.
