The Panasonic AM1305F is a switching regulator IC designed for use in DC-DC converters. It features built-in enhanced features such as soft-start, fault-short protection, and internal temperature-sensing circuit to protect against overheat. This part is ideal for applications such as low-voltage, low-power and high-efficiency DC-DC converters. It operates with a wide input voltage range of 4.5V to 28V, a maximum output current of 3A, and delivers a regulated, ripple-free output voltage of 1.5V to 25V. Additionally, it was designed with a high switching frequency of 3 MHz, enabling small components and a low-noise level in the system.
