The IR38263MTRPBFAUMA1 is a member of the DC/DC Switching Regulators product family from Infineon Technologies. This fully integrated circuit device is designed for use in a variety of applications, such as automotive, industrial, lighting, consumer electronics and telecom. It includes two200-mA Power MOSFETs, voltage and current regulation, protection circuits, and a microcontroller-based digital control to provide a complete and well-integrated DC-DC switching regulator solution.

It operates as a step-down regulator, taking a higher input voltage of 6V and outputting a 5V steady output. In addition, the regulator provides excellent line and load regulation performance when operated with a wide VIN range of 9V to 16V, and maintains a stable output voltage with low output ripple. The device offers the ultimate in performance for both step-up and down applications, and provides an optimized solution for a wide variety of different types of applications.

The IR38263MTRPBFAUMA1 is designed to offer an optimized and cost effective solution for a wide variety of consumer and industrial applications. The device is capable of regulating input voltages ranging from 9V to 16V and offers an adjustable output voltage ranging from 0.9V to 5.5V for reference and system voltages within the same device. Its high efficiency and low cost make it an ideal choice for many consumer and industrial applications, including automotive power systems, consumer electronics and industrial automation.

The primary benefit of the IR38263MTRPBFAUMA1 is its extremely compact size. It measures just 5.6 by 6.6 mm, making it a perfect fit for many applications with limited space. The device also provides an extremely low quiescent current of just 10 µA, a fast transient response and an ultra low standby current of less than 200 nA. This makes it perfect for battery powered applications that require long run times, such as portable electronics.

The IR38263MTRPBFAUMA1 uses a high-speed synchronous rectifier to achieve high efficiency performance, with efficiencies exceeding 95% in many designs. The device features an optional 2-cycle output for improved noise suppression, and is designed to be used in both buck and boost configurations. The device provides accurate output voltage regulation with excellent line and load regulation for all output voltage settings.

In terms of protection, the IR38263MTRPBFAUMA1 provides both over-current protection (OCP) and over-voltage protection (OVP). The over-current protection is provided by the two external current limit resistors that limit the output current during an overload situation. The over-voltage protection is enabled by the built-in on-chip regulator that limits the output voltage to the set voltage. Additionally, the device provides protection against short-circuit, enable/disable and thermal shutdown.

The IR38263MTRPBFAUMA1\'s working principle is based on the Buck-Boost topology, which utilizes a high-frequency switching between the input and the output. The device\'s switch-mode circuitry allows the current source and sink at the output to rapidly and accurately regulate the output voltage. To regulate the output voltage, the device uses the integrated microcontroller that receives feedback from an external sense resistor, which is typically connected between the output and ground, and controls an N-channel MOSFET to regulate the output voltage.

The IR38263MTRPBFAUMA1 is a high-performance, cost effective solution for many consumer and industrial applications. Its highly efficient synchronous-rectified buck-boost topology enables this device to deliver optimal power and performance in an ultra-compact package, without compromising the reliability and protection in the circuit. This makes it an excellent choice for many of today\'s most demanding applications.
