DESCRIPTION
The PTN04050C is a 4-pin boost-voltage regulator product. In new designs it should be considered in place of
the PT5040 series of positive step-up products. The PTN04050C is smaller and lighter than its predecessors,
and has either similar or improved electrical performance characteristics. The case-less, double-sided package,
also exhibits improved thermal characteristics, and is compatible with TI
's roadmap for RoHS and lead-free
compliance.
Operating over a 2.95V to 5.5V input range, the PTN04050C provides high-efficiency, step-up voltage conversion
for loads of up to 12W. The output voltage is set using a single external resistor. The PTN04050C may be set to
any value within the range, 5V to 15V. The output voltage of the PTN04050C can be as little as 0.5V higher than
the input, allowing an output voltage of 5V, with an input voltage of 4.5V.
The PTN04050C modules are suited to a wide variety of general-purpose applications that operate off 3.3-V or
5-V dc power.
