ISL6416IA-TK, an advanced high performance single device PMIC (Power Management Integrated Circuit) linear voltage regulator, is designed to meet the needs for lower power consumption and improved performance in point of load (pol) applications. This application field is a high-density circuit with multiple outputs supplied by a single voltage bus. The device offers can be used on large current and complex voltage regulation requirements in the field of consumer, industrial and automotive grade markets. This device has integrated a high-efficiency DC-DC continuous mode (CM) converter with a low-dropout regulator (LDO), enabling high power transfer efficiency and automated sleep mode.

The operating principle of the ISL6416IA-TK is based on the use of its built-in CM converter and LDO circuit. The CM converter is responsible for transforming a wide range of input voltages from 4.5 to 14 V into a regulated voltage of 5.5V. Its features include low-dropout voltage, low quiescent current, fast transient response and a wide input voltage range. The device has an internal P-channel MOSFET for control and a resistor divider for setting the output voltage. The power transfer efficiency of this converter depends on the operation mode.

The LDO circuit enables a stable output of 3.3V from the input voltage of 4.5 to 14V. This regulation is achieved through the voltage reference of the device and the use of an internal PMOS FET pass element. The output regulation is proportional to the load within the range set by internal reference voltage and the external load resistance.

The ISL6416IA-TK features integrated thermal protection, over current protection and under voltage lockout (UVLO) protection for greater safety and reliability. Furthermore, the device also provides an adjustable phase compensation that allows the optimization of stability performance. The device also offers multiple power-on options, enabling different types of system on behavior such as soft-start and step start.

In conclusion, the ISL6416IA-TK is a cost-effective single PMIC linear voltage regulator designed for point of load applications. Its advantages are the integrated DC-DC converter and LDO, low quiescent current, wide input voltage range and multiple protection features. These features make it ideal for applications including consumer, industrial and automotive grade markets.
