LTC3100 - Linear Technology

LTC3100 1.5MHz Synchronous Dual Channel DC/DC Converter and 100mA LDO

The LTC®3100 combines a high efficiency 700mA synchronous step-up converter, a 250mA synchronous stepdown converter and a 100mA LDO regulator. The LTC3100 features a wide input voltage range of 0.65V to 5V. The step-down converter can be powered by the output of the step-up converter or from a separate power source between 1.8V and 5.5V. The LDO can also be .
