The ETA1036 is a high efficiency synchronous step-up
converter that can provide up to 3W of power to a boosted
output from a low voltage source. Unlike most step-up
converter, not only it starts up at a very low input voltage
as low as 0.85V, it also 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. The ETA1036 starts up from a
voltage as low as 0.85V making it ideal for applications with
single-cell or two-cell alkaline, NiCd, and NiMh batteries. A
switching frequency of 2MHz 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. ETA1036 is available in
three output voltage options. They are 2.1V, 3.3V and 5V. It
is housed in a tiny SOT23-5 package.
