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

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.
