Infineon Technologies AG Voltage Regulators - DC DC Switching Regulators IR3477MTRPBF

The IR3477MTRPBF is a fully integrated DC/DC voltage regulator designed for high efficiency and ease of use. It operates within an input voltage range of 3V to 27V and can provide an adjustable output voltage from 0.5V to 12V, supporting continuous load capabilities of up to 15A. The device features constant on-time control, eliminating the need for external compensation loops, and offers programmable switching frequency and soft start functionality. Key protective features include thermally compensated over current protection, under/over voltage fault protection, and thermal shutdown. The regulator also includes a power good output and an enable input with voltage monitoring capability, making it suitable for a variety of applications, including notebook and desktop computers, consumer electronics, and distributed power systems. The compact 5mm x 6mm QFN package enhances its suitability for space-constrained designs.
