Description
The ATH06T033 series is one of the
smallest non-isolated power modules that
features Auto-Track™. Auto-Track™
simplifies supply voltage sequencing in
power systems by enabling modules to track
each other, or any other external voltage,
during power up and power down.
Although small in size (0.87 in × 0.5 in),
these modules are rated for up to 6 A of
output current, and are an ideal choice in
applications where space, performance,
and a power-up sequencing capability are
important attributes.
The product provides high-performance
step-down conversion from a 3.3-V input
bus voltage. The output voltage of the
ATH06T033 can be set to any voltage
over the range, 0.8 V to 2.5 V, using a
single resistor.
Other operating features include an
on/off inhibit, output voltage adjust (trim),
and output over-current protection. For
high efficiency these parts employ a
synchronous rectifier output stage, but a
pre-bias hold-off capability ensures that
the output will not sink current during
startup.
Target applications include telecom,
industrial, and general purpose circuits,
including low-power dual-voltage systems
that use a DSP, microprocessor, ASIC, or
FPGA.
Package options include both through-
hole and surface mount configurations.
