LTC3426 - 1.2MHz Step-Up DC/DC Converter in SOT-23

DP-SWREG/Monolithic CUT TAPE 1.2 MHz Step-Up DC/DC Converter

The LTC3426 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. Anti-ringing 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 device features very low shutdown current of 0.5µA. The LTC3426 is available in the 6-lead SOT-23 package. Protected by U.S. Patents, including 6498466, 6611131 Applications White LED Driver Supply Local 3.3V or 5V Supply Battery Back-Up
