1μA Ultra low Iq, 0.8V Startup,1A Synchronous Boost DESCRIPTION ETA1064 is a high efficiency synchronous step-up converter with ultra-low quiescent current down to 1μA. It is capable of delivering at least 2W of power from a low voltage source, i.e. 0.4A 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 1.4MHz minimizes solution footprint by allowing the use of tiny and low profile inductors and ceramic capacitors. An internal synchronous MOSFET provides highest efficiency and with a current mode control that is internally pensated, external parts count is reduced to minimal. With the ultra-low Iq feature, ETA1064 is ideal for solution that requires low standby power and pact board size such as Io T applications. ETA1064 is housed in a SOT23-6 and DFN2x2-6 package Features - Ultra low IQ when No Switching :1u A for adjustable version and 1.2u A for fixed voltage version - 0.8V Startup - 5V/0.4A Output Capability at Vin=3V - Output to Input Reversed Current Protection - Up to 94% Efficiency - Internal Synchronous Rectifier and Output Disconnect - Short-circuit Protection - Adjustable version and Fixed voltage version - SOT23-6 & DFN2x2-6 Package APPLICATIONS - Tablet, MID - Smart Phone - Power Bank TYPICAL APPLICATION VIN ENABLE 2.2 u H 4.7 u F 6 SW OUT 1 4 IN ETA1064 FB 5 3 EN GND 2 22 p F optional R1 10 u F...
