The ISL6336DIRZ is an interpretation of the Special Purpose Voltage Regulator category of Power Management Integrated Circuit (PMICs). It provides the power management functions for a wide range of application fields. The device is highly configurable and includes several features such as output voltage and current regulation, system start up and power sequencing, fault and current limit protection, hot swap and controlling, leakage current limitation, and symmetrical switching. The device is a synchronous step-down buck regulator that operates from a 5V to 14V input and drives a configurable output voltage in a 1.5V to 6V range. It is specially design to support multi-phase applications. Its integrated synchronous rectifier FETs and current sense resistors guarantee the lowest possible R_DSON and associated conduction losses. Its fully adjustable current and over-temperature protection is integrated to ensure maximum reliability. The ISL6336DIRZ device has a wide range of application fields, such as notebook and desktop computers, industrial and distributed power systems, as well as embedded systems with high current requirements. It also finds uses in IOT and automotive applications. The built-in features allow the IC to provide accurate voltage and current control over a wide temperature range from -40°C to 125°C. The IC also includes several functions and features to improve system efficiency and reduce thermal stress. The working principles of the ISL6336DIRZ device depend on its implementation. In multi-phase applications, the device is embedded in a negative-charge pump voltage regulator circuit. The IC can be configured to provide a combination of one, two, three and four-phases. In each phase, separate controller cores generate the pulse width modulated (PWM) signals, enabling independent control of each phase. The compensation network is used to provide the desired gain and phase shift to ensure proper regulator operation. It consists of an internal resistor and external filter cap, or an external resistor and filter cap. Proper selection and tuning of components will ensure optimal transient response, line and load regulation, as well as current limit accuracy. The ISL6336DIRZ can also be used to power isolated output systems. In this application, a self-oscillating converter is used to generate the isolated output voltage. It can also provide additional synchronization signals to enable the use of additional protection circuits.This device takes advantage of its integrated features to reduce overall system costs. In multi-phase applications, the control signal for each phase is independently adjustable, enabling lower component counts and improved system efficiency. It is also capable of combining with other PMICs to create a complete power supply solution. It has been designed to enable fast system start-up and works with various input protection schemes.In conclusion, the ISL6336DIRZ is a highly integrated and configurable step-down voltage regulator that is suitable for a wide range of application fields. Its advanced built-in features guarantee maximum system reliability and transient accuracy. It is also capable of powering isolated output systems, making it an ideal solution for any system requiring precise voltage regulation.
