SOT23-6 Package

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. Unlike most step-

up 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. This eliminates the need

for an external MOSFET and its control circuitry to

disconnect the input from output, and provides robust

output overload protection. And ETA1039 also provides

the flexibility of setting input peak current limit and

thus, output current is limited.

APPLICATIONS

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.



USB OTG for MIDs, Smartphones

Mobile back-up Battery Chargers

Alkaline, NiCd, and NiMh batteries applications

USB powered devices
