ISL6556BCRZ-T is a special purpose Voltigate Regulators (PMIC) that are featured by their low output noise, low quiescent current and excellent line and load regulation capabilities. It is designed to replace the discontinued LDO regulators and is suitable for a variety of applications such as in high frequency and high precision mixed signal and RF circuits.

This integrated circuit (IC) contains an on board low dropout regulator, PWM controller, MOSFET switch and an adjustable current limit amplifier along with a robust package for ease of use. It is designed to support up to 6A in automotive, industrial and commercial power systems. The IC offers adjustable current limit, accurate voltage regulation and thermal protection, as well as a watchdog timer. The low quiescent current of 10 uA allows the IC to be powered while in-vehicle, while the protection features provide the extra safety and protection against any possible short circuits.

The ISL6556BCRZ-T is suitable for a variety of applications such as automotive electronics, automotive entertainment systems, automotive powering, industrial and commercial networks, energy management systems, and LED/LCD displays. It can be used in a variety of environments due to its wide operating temperature range of -40 to +125°C. It is best suited for applications where low output noise and low quiescent current are needed, and its excellent line and load regulation capabilities make it ideal for applications where a precise voltage is required. The ISL6556BCRZ-T offers a good combination of low EMI and dropout voltage which makes it suitable for high frequency and communication systems.

The ISL6556BCRZ-T works by using its fixed 5V reference voltage to monitor and regulate output voltage. When the output voltage deviates from the desired level, the IC will try to compensate for the difference. The voltage regulation is achieved by using the PFM/PWM based control circuit and a load sharing switch. The PFM/PWM control circuit consists of an internal current limit amplifier which sets the wattage or current limit, and an internal PWM wave generator which provides a varying mark/space ratio based on the reference voltage. The PWM waveform is then used to drive one or both of the two MOSFETs, depending on if the ISL6556BCRZ-T is configured in single or dual ramp mode.

The IC further provides protection features such as short circuit protection, over-temperature protection and over-voltage/under-voltage protection. The short circuit protection prevents the IC from entering into a destructive current loop and the over-temperature protection using a temperature sensor prevents overheating due to high current demand. An adjustable watch dog timer is also provided which can be used to reset the IC in case the load exceeds the maximum limit defined. This timer is used to actively monitor the voltage output levels and can be configured for different time intervals.

Overall, the ISL6556BCRZ-T is a robust, low noise and low power special purpose Voltigate Regulator from Intersil Corporation. Its high performance and protection features, along with its wide temperature range, makes it suitable for a variety of applications where precise control over the output voltage is important, such as in automotive and industrial circuits. Its wide range of features makes the ISL6556BCRZ-T a great choice for high frequency, communication and precision mixed signal circuits.
