The ISL60002CIH312-TK is a part of Intersil\'s Programmable Regulator and Voltage Reference family. It is a precision programmable regulator and voltage reference family optimized for low voltage low power applications, such as volatile memories and portable battery-powered devices. It offers an 8-bit DAC with an output voltage range of 0.8V to 5.5V and a programmable slew rate up to 80V/μs, as well as programmable output current limiting. It is ideal for providing precision regulated supply voltages in high current applications.

The ISL60002CIH312-TK has multiple application fields including PCI Express systems, low power memories, battery powered systems, portable data storage, and automotive applications. It is designed to replace traditional voltage references and voltage regulators and offer improved system accuracy and reliability with lower power consumption. It can provide precisely regulated output voltage and current, with high accuracy and repeatability, and is suitable for use in both power constrained and performance-critical applications.

The working principle of the ISL60002CIH312-TK is that it uses an 8-bit DAC (Digital to Analog Converter) to generate an output voltage that is monitored and controlled by the programmable logic. This is achieved by connecting the positive pad of an internal voltage reference to the inverting input of the error amplifier, and the output of the DAC to the non-inverting input of the error amplifier. The output of the error amplifier is then connected to the compensation pin of the output stage, which controls the output voltage. The voltage reference is used to generate a stable reference voltage, which is used to compare to the DAC output and adjust the output voltage accordingly.

The programmable logic determines the output voltage and slew rate, with the output voltage being adjustable from 0.8V to 5.5V and the slew rate programmable up to 80V/μs. Additionally, the current limit of the output stage is also programmable, ranging from 0mA to 800mA. All these features ensure that the output voltage and current remain stable and within precise specifications.

In summary, the ISL60002CIH312-TK is a precision programmable regulator and voltage reference ideal for low voltage low power applications. It offers precise voltage and current output control, with high accuracy and repeatability, making it suitable for use in both power constrained and performance-critical applications. Additionally, it provides controllable output voltage and current, precise output voltage and current regulation, and programmable slew rate and output current limiting.
