Infineon Technologies AG Voltage Regulators - DC DC Switching Regulators IR3863MTRPBF

The IR3863MTRPBF is a highly integrated synchronous buck regulator designed for a wide input voltage range of 3V to 21V and capable of delivering a continuous output current of 6A. It features an output voltage range from 0.5V to 12V, making it suitable for various applications including notebook and desktop computers, game consoles, and consumer electronics. This regulator employs constant on-time control and does not require external compensation, simplifying design efforts. It includes programmable switching frequency, soft start functionality, and thermally compensated overcurrent protection. Additional features such as pre-bias startup, a precision voltage reference with a tolerance of +/-1%, and under/over voltage fault protection enhance its reliability and performance. The device is housed in a compact 4mm x 5mm QFN package, making it a space-efficient solution for power management in compact electronic designs. The IR3863MTRPBF is particularly well-suited for battery-powered applications due to its excellent efficiency at low output currents.
