ETA1069 - Supper High Efficiency Synchronous Boost

Datasheet Summary

Description

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.

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.
