SOT23-5 packageDescraption:
The STI3411A is a 1.0MHz constant frequency,
current mode step-down converter. It is ideal for
portable equipment requiring very high current up to
2A from single-cell Lithium-ion batteries while still
achieving over 90% efficiency during peak load
conditions. The STI3411A also can run at 100% duty
cycle for low dropout operation, extending battery life
in portable systems while light load operation
provides very low output ripple for noise sensitive
applications. The STI3411A can supply up to 2A
output load current from a 2.3V to 6V input voltage
and the output voltage can be regulated as low as
0.6V. The high switching frequency minimizes the
size of external components while keeping switching
losses low. The internal slope compensation setting
allows the device to operate with smaller inductor
values to optimize size and provide efficient
operation. The STI3411A is offered in a low profile
(1mm) 6-pin, thin SOT package, and is available in
an adjustable version.
This device offers two operation modes, PWM
control and PFM Mode switching control, which
allows a high efficiency over the wider range of the
load.
