Win Source Electronics PMIC - PMIC - Voltage Regulators - DCDC Switching Regulators - LTC3440EDD#PBF 303334-LTC3440EDD

The LTC3440EDD#PBF is a high-efficiency Buck-Boost DC/DC converter designed for applications requiring input voltages that may be above, below, or equal to the output voltage. It supports a continuous output current of up to 600mA and operates within an input and output voltage range of 2.5V to 5.5V. The device features synchronous rectification, achieving efficiencies of up to 96%, and has a low quiescent current of 25¬µA in Burst Mode operation, which is beneficial for battery-powered devices. The LTC3440 allows for programmable switching frequencies from 300kHz to 2MHz, with the capability to synchronize to an external clock. It includes essential features such as thermal shutdown, current limit protection, and a shutdown current of less than 1¬µA. The product is available in compact 10-pin MSOP and DFN packages, making it suitable for space-constrained applications like handheld instruments, digital cameras, and palmtop computers. The operating temperature range is specified from -40¬8C to 85¬8C, ensuring reliability in various environments.
