The Infineon IR3899MTRPBF is a 12V input, 9A Step-Down Voltage Regulator manufactured with the company’s patented SupIRBuck technology. This single-channel device is designed to provide a regulated output voltage in applications requiring a maximum output current of 9A. It features advanced multiphase interleaving, extremely fast transient response, excellent loop stability, and a wide operating temperature range to promote maximum system efficiency and reliability. Its symmetric current-mode control architecture reduces the need for large output capacitors, while its synchronous rectification structure results in very low losses and improved system efficiency. The IR3899MTRPBF is fully protected against overvoltage, undervoltage, overcurrent, and short circuit events.
