Product Summary

The LTC3426ES6#T is a Step-Up DC/DC Converter. The LTC3426ES6#T step-up switching regulator generates an output voltage of up to 5.5V from an input voltage as low as 1.6V. Ideal for applications where space is limited, it switches at 1.2MHz, allowing the use of tiny, low cost and low profile external components. Its internal 2A, 100mΩ NMOS switch provides high efficiency even at heavy load, while the constant frequency, current mode architecture results in low, predictable output noise that is easy to filter. Antiringing circuitry reduces EMI concerns by damping the inductor while in discontinuous mode, and internal soft-start eases inrush current worries. Internal frequency compensation is designed to accommodate ceramic output capacitors, further reducing noise. The LTC3426ES6#T features very low shutdown current of 0.5μA. The applications of the LTC3426ES6#T include White LED Driver Supply, Local 3.3V or 5V Supply and Battery Back-Up.
