The ISL8130IRZ is a High-Frequency Voltage Mode PWM Controller developed by Intersil Corporation. It is designed to provide complete control and drive functions for various voltage regulation circuits, DC-DC converters and power supplies. The ISL8130IRZ controller is a highly integrated device which consists of a voltage-mode pulse-width modulation (PWM) controller, with frequency jitter and a programmable frequency. It also includes several system protection features such as under-voltage lockout (UVLO), soft-start, over-current protection (OCP), and over-temperature protection (OTP).

The ISL8130IRZ is suitable for applications such as voltage regulation in telecoms, automotive, computer system peripheral, PCI Express, intermediate and off-line power supplies. More specifically, it is well suited for isolated DC/DC converters, DC/DC converters with Auxiliary Power, Preset Voltage/Current Regulators, Constant Voltage/Current Regulators, switching polynomial regulators, DC/DC controllers, surge suppressors, uninterruptible power supplies and off-line AC/DC converters.

The ISL8130IRZ operates by using the voltage mode control method, which allows it to respond quickly to changes in load or input voltage. The device enables precise regulation of output voltage, while providing a fast transient response and excellent line and load regulation. In addition, the ISL8130IRZ also offers an adjustable oscillation frequency, which allows the device to operate over a wide temperature range.

The ISL8130IRZ features a variety of protection features, such as short-circuit protection (SCP), soft-stop and over-voltage protection (OVP). The SCP feature shuts down the supply to protect the load if it is shorted. The OVP feature is designed to prevent the output voltage from rising too high in case of a fault condition. The soft-stop feature is used to prevent an overshoot of the output voltage, which could cause damage to sensitive loads.

The ISL8130IRZ also includes current-mode control with external compensation andan internal slope compensation, allowing for improved efficiency and reduced EMI. This controller also features a programmable soft-start, allowing the user to set the start-up time for a steady voltage output. The ISL8130IRZ also features programmable UVLO, which turns off the supply when the input voltage is below a certain threshold. These features make the ISL8130IRZ ideal for a wide range of applications.

Overall, the ISL8130IRZ is a highly integrated DC/DC controller capable of providing precise voltage regulation and fast transient response. It offers many protection features, adjustable oscillation frequency, current-mode control and a programmable soft-start, making it an excellent choice for a wide range of applications.
