The ISL6522IRZ-TKS2698 is a DC-DC Switching Controller specifically designed for voltage regulation of power supplies and other industrial applications. The controller relies on PWM control, allowing for precise control of the output voltage. The device is available in both an 8-pin SOIC package and a 10-pin MSOP package for ease of assembly and integration.

It is capable of a wide range of output voltage regulation in both positive and negative polarities. It is also designed to operate at a wide range of switching frequencies with a maximum of 2.2 MHz. The switching FET drivers of the device have integrated level shifters which allow them to combine with the external MOSFET drivers.

The ISL6522IRZ-TKS2698 is a highly reliable and efficient device making it suitable for multiple applications such as industrial control, automotive, consumer electronics, wireless applications, server and proprietary computer power management, among others. The PMIC features a high-side and low-side driver for bidirectional capability. It has an adjustable overhead voltage for high-side and low-side drivers, which help in precise regulation of voltage by limiting current turn-on and turn-off rate.

The ISL6522IRZ-TKS2698 also includes an analog interface that allows the user to set the desired output voltage. The device also employs soft start functionality to control in-rush current. This device is designed for step-down operation and offers protection against inductor core over saturations, open loop conditions, output overvoltage and over-temperature.

The ISL6522IRZ-TKS2698 uses a PWM control loop to keep the output voltage in regulation. The adjustable current limit prevents overload situations that would otherwise lead to excessive power dissipation and system instability. The PWM oscillator can be programmed using the adjustable control voltage or the external resistor. The device is also capable of operating in a pulse-skipping mode to reduce input power and increase efficiency.

The ISL6522IRZ-TKS2698 can be used with a wide range of power supplies. It is designed to operate within a wide input voltage range and can provide a programmable output current of up to 0.8 A. The device also features under-voltage lockout, current limiting, thermal shutdown, and short-circuit protection.

The ISL6522IRZ-TKS2698 is a highly versatile DC-DC Switching Controller specifically designed for voltage regulation of power supplies. With its wide range of switching frequencies, adjustable output voltage and current limit, and built-in protection functions, the device is suitable for multiple applications.
