LTC3561AIDD#PBF

The LTC3561AIDD#PBF is a high-efficiency synchronous buck-boost converter designed to provide a regulated output voltage, even when the input voltage is lower, higher, or equal to the output voltage. This makes it an ideal choice for applications requiring a wide input voltage range. The converter operates at a fixed frequency of 2.25MHz, which allows the use of small external components, resulting in a compact and space-saving solution. The high switching frequency also minimizes the size of the external inductor, further reducing the overall footprint of the system. This buck-boost converter provides a 400mA continuous load current with a typical quiescent current of only 25μA, making it highly efficient and suitable for battery-powered applications. It offers a wide input voltage range of 1.8V to 5.5V and can output voltages ranging from 2.5V to 5.25V. Additional features of the LTC3561AIDD#PBF include overtemperature protection, undervoltage lockout, and soft-start to prevent inrush current during start-up. The device is available in a small 10-pin DFN package, making it suitable for space-constrained applications, such as portable devices and battery-powered systems. Overall, the LTC3561AIDD#PBF offers high efficiency, flexibility, and compactness, making it an excellent choice for various voltage conversion requirements.
