ISL95338IRTZ is a DC-DC switching regulator controller manufactured by Intersil that is designed for the Point-Of-Load (POL) regulator applications. It is a fully integrated, high efficiency, dual output core and exposed pad integrated circuit (IC) that provides excellent load regulation, as well as various safety features. It is capable of delivering up to 5A of current to two independently controlled outputs, making it one of the most efficient DC-DC regulators on the market.

The ISL95338IRTZ features a high-efficiency internal PWM controller and two high-side power MOSFETs, integrated on-chip compensation, and enhanced thermal protection. Its high-efficiency internal PWM controller can provide up to 96% efficiency, making it suitable for a wide range of applications including telecommunication, automotive, and computer peripherals.

The ISL95338IRTZ operates from an input voltage range of 4.5V to 18V and provides two independently adjustable and both programmable output voltages from 0.6V up to 5V. In addition, it offers a wide range of protection features such as short circuit protection and overvoltage protection. It also provides an easily adjustable soft-start feature to eliminate current surge during startup, as well as an adjustable current limit feature to protect the output from inrush currents.

The ISL95338IRTZ includes several features to ensure stability and high-efficiency operation, including a low-side MOSFET driver, integrated on-chip compensation, and high frequency oscillator. The on-chip compensation allows the designer to adjust the duty cycle of the PWM, resulting in improved efficiency and improved load regulation. In addition, the high frequency oscillator allows the designer to reduce component count and size while still meeting efficiency requirements.

In addition to its many features, the ISL95338IRTZ is also designed to meet stringent thermal requirements. It is designed with a thermal foldback feature to reduce output power in case of overload, and has an integrated thermistor to accurately detect temperature changes. It is also capable of operating in high-temperature environment up to 85°C.

Overall, the ISL95338IRTZ is an efficient, high performance DCDC switching regulator controller that is well suited for a wide range of applications. Its numerous features, including integrated PWM control and on-chip compensation, thermal protection, and high-efficiency operation make it an ideal choice for power management and POL applications.
