Description
The PTH03000 series of non-isolated
power modules are small in size and high
on performance. Using double-sided surface
mount construction and synchronous
rectification technology, these regulators
deliver up to 6 A of output current while
occupying a PCB area of about half the
size of a standard postage stamp. They
are an ideal choice for applications where
space, performance and cost are important
design constraints.
The series operates from an input
voltage of 3.3 V to provide step-down
power conversion to any output voltage
over the range, 0.9 V to 2.5 V. The output
voltage of the PTH03000W is set
within this range using a single resistor.
Operating features include an on/off
inhibit, output voltage adjust (trim), an
output current limit, and over-temperature
protection.
Target applications include telecom,
industrial, and general purpose circuits,
including low-power dual-voltage systems
that use a DSP, microprocessor, or ASIC.
Package options include both throughhole
and surface mount configurations.
