ETA ETA1039
The ETA1039 is a high efficiency synchronous step-up converter that can provide up to 1.5A to a fixed output up to 5V from a low voltage source. This eliminates the need for an external MOSFET and its control circuitry to disconnect the input from output, and provides robust output overload protection. ETA1039 is housed in a tiny SOT23-6 package.| Part No. | ETA1039 |

DESCRIPTION
Unlike most stepup converter, it incorporates circuits that disconnect the input from output, during shutdown, short-circuit, output current overloading, or other events when output is higher than the input. And ETA1039 also provides the flexibility of setting input peak current limit and thus, output current is limited. 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 highest efficiency and with a current mode control that is internally compensated, external parts count is reduced to minimal. ETA1039 is housed in a tiny SOT23-6 package.FEATURES
