钰泰 ETA1039 SOT23-6 电池充电管理芯片

DESCRIPTION
The ETA1O39 is a high efciency synchronous step-up
 converter that can provide up to 1.5A to a fixed output
upto5Vfromalow 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
ETAIO39 also provides the flexilty of setting input
peak current limit and thus, output current is limited.
A switching frequency of |MHz minimizes solution
footprint by alowing the use of tiny and low profile
inductors and ceramic capacitors. An internal
synchronous MOSFET provides highest eficincy and
with a current mode control that is interally
compensated, external parts count is reduced to
minimal.

ETAIO39 is housed in a tiny S0T23-6 package.
