The 1314560-R1232D121B-TR-FE is a CMOS-based PWM step-down DC/DC converter designed for efficient voltage regulation in portable electronic devices. It features a fixed output voltage of 1.2V and operates within an input voltage range of 2.6V to 5.5V. The device supports a maximum output current of 1.4A and incorporates a synchronous rectifier for improved efficiency. The switching frequency is set at 2.25MHz, allowing for the use of smaller inductors, which is beneficial for space-constrained applications. The IC includes built-in protection features such as a current limit circuit and a latch-type protection mechanism to safeguard against over-current conditions. It operates over a temperature range of -40¬8C to 85¬8C, making it suitable for various environmental conditions. The package type is 8-SON, which is compatible with surface mount technology. This product is ideal for applications requiring a reliable power source, such as PDAs, digital cameras, and notebook PCs.
