PTN04050C,pdf(12-W 3.3/5-V Inp

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.
