Description
The PTH05050 is one of the smallest
non-isolated power modules from Texas
Instruments that features Auto-Track鈩?
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
脳
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 5-V input
bus voltage. The output voltage of the
PTH05050W can be set to any voltage
over the range, 0.8 V to 3.6 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.
