IR38060MTRPBF is a switching regulator with incomparable performance and features for voltage regulation applications. It is designed for use in a wide variety of electronic applications including embedded systems, cellular base stations, and industrial automation and control systems. The IR38060MTRPBF is a high-efficiency, monolithic integrated circuit that utilizes a constant-frequency, current-mode control technique. It is designed to provide excellent load and line regulation, transient response, and output voltage accuracy.

The IR38060MTRPBF consists of an internal error amplifier, current-sense comparator, voltage reference, switching regulator, and MOSFET driver. The IC also includes a differential input filter that provides low noise performance with minimal external components. The switching regulator is based on a hysteretic current-mode control architecture, which enables a fast response and stable loop. The feedback control loop is set with the help of a resistor divider.

The IR38060MTRPBF has a wide input voltage range from 5.5 V to 20 V and offers both short-circuit protection and thermal protection features. The output voltage can be set anywhere from 0.8 V to 5.25 V in 0.25 V increments and can be trimmed with a selectable precision resistor. Output current is adjustable up to 3 A, and the output voltage ripple is less than 1 mV.

The IR38060MTRPBF is ideal for applications requiring up to 3 A of regulated output current such as DC/DC converters, power management systems, LED drivers, and battery-powered systems. It is also suitable for fast transient applications where precision and accuracy are key. Additionally, it can provide ultra-low noise operation with minimal board space.
