PTH12050 pdf datasheet

The PTH12050 series is the smallest
non-isolated power modules from Texas
Instruments that features Auto-Track™
Sequencing. Auto-Track simplifies the
sequencing of supply voltages 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 series operates from an input
voltage of 12-V to provide step-down
conversion to a wide range of output voltages.
The output voltage of the W-suffix
device may set to any voltage over the
adjust range, 1.2 V to 5.5 V. The L-suffix
device has an adjustment range of 0.8 V
to 1.8 V. The output voltage is set within
the adjustment range using a single external
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.
Target applications include telecom,
industrial, and general purpose circuits,
including low-power dual-voltage systems
that use a DSP, microprocessor, ASIC, or
FPGA.
