ETA1069
ETA1069 is a high efficiency synchronous step-up converter with ultra-low quiescent current down to 1.2μA. It is capable of delivering at least 3W of power from a low voltage source, i.e. 0.6A at 5V output. It also features a true-shutoff function that disconnects the input from output, during shutdown and output short-circuit conditions. This eliminates the need for an external MOSFET and its control circuitry to disconnect the input from output and provides robust output overload protection.
A switching frequency of 1MHz minimizes solution footprint by allowing the use of tiny and low profile inductors and ceramic capacitors. An internal synchronous MOSFET provides high efficiency and with a current mode control that is internally compensated, external parts count is reduced to minimal. With the ultra-low IQ feature, ETA1069 is ideal for solution that requires low standby power and compact board size such as IoT applications.
ETA1069 is available in a SOT23-6 ,DFN2x2-6 package
