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 2.95 V to 5.5 V input range, the PTN04050C provides high-efficiency, step-up voltage
conversion for loads of up to 12 W. The output voltage is set using a single external resistor. The PTN04050C
may be set to any value within the range, 5 V to 15 V. The output voltage of the PTN04050C can be as little as
0.5 V higher than the input, allowing an output voltage of 5 V, with an input voltage of 4.5 V.
The PTN04050C modules are suited to a wide variety of general-purpose applications that operate off 3.3-V or
5-V dc power.
