The ISL6420AIRZ are DC/DC switching controllers designed to allow multiple output power rails and improved power efficiencies. It is a part of the PolarRAMP family of power controllers from Intersil Corporation. The ICs integrate a full bridge driver, bi-directional digital current sense amplifier and soft-start circuitry. It also offers digital power tracking feature which allows efficient module-level power management and digital access to current and temperature sensing for reliable over-current and over-temperature protection.

The ISL6420AIRZ is suitable for applications that require reliable, high efficiency and at the same time cost-sensitive DC-DC power supplies. Notable applications include optical storage devices like Blu-Ray and DVD players, multi-output DC/DC converters, and PLC power modules.

The ISL6420AIRZ works using the voltage mode control principle. The main functional block of this IC is a voltage mode current-mode (VMCM) control loop. This loop combines an analog error amplifier, a pulse width modulator (PW), and a driver circuit. In use, the error amplifier compares the error voltage to the voltage reference and produces an error signal for the PW. The PW then adjusts the PWM duty cycle and controls the motor current. The output from the PW is then sent to the driver circuit, which controls the power switch. This power switch then supplies power to the load.

The ISL6420AIRZ comes with a variety of features such as an external VCC supply, internal zener clamping, soft start control and external voltage sense, making it an ideal choice for multiple output applications. Additionally, it features low current consumption, minimum component count and wide temperature range operations. It comes in a 56-lead LQFP package and 4mm x 4mm QFN packages.

In summary, the ISL6420AIRZ is a switching controller designed for multiple output DC/DC applications. It offers improved power efficiency and digital power management. It also offers versatile features such as low current consumption, minimum component count, wide temperature range operations and voltage sensings. It is suitable for applications such as optical storage, multi-output DC/DC converters, and PLC power modules.
