1μA Ultra low Iq, 0.8V Startup,1A Synchronous Boost

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 shutdow • Ultra low IQ when No Switching :1uA for adjustable version and 1.2uA for fixed voltage version\n\n• 8V Startup\n\n• 5V/0.4A Output Capability at Vin=3V\n\n• Output to Input Reversed Current Protection\n\n• Up to 94% Efficiency\n\n• Internal Synchronous Rectifier and Output Disconnect\n\n• Shor;

4-digit LED-driver with I2C-Bus interface

GENERAL DESCRIPTION The LED-driver is a bipolar integrated circuit made in an I2L compatible 18 volts process. The circuit is especially designed to drive four 7-segment LED displays with decimal point by means of multiplexing between two pairs of digits. It features an I2C-Bus slave transceive
