The PTN04050A is an adjustable output, positive-to-negative, integrated switching regulator. In new designs, it
should be considered in place of the PT5020 series of positive-to-negative integrated switching regulator
products. The PTN04050A is smaller and lighter than its predecessor, with improved electrical performance
characteristics, while operating over a wider input voltage range, with an adjustable output voltage. The
caseless, double-sided package also exhibits improved thermal characteristics, and is compatible with TI's
roadmap for RoHS and lead-free compliance.
Operating from a wide-input voltage range of 2.9 V to 7 V, the PTN04050A provides high-efficient,
positive-to-negative voltage conversion for loads of up to 6 W. The output voltage is set using a single external
resistor, and may be set to any value within the range, –15 V to –3.3 V.
The PTN04050A features include on/off inhibit, undervoltage lockout, over-current protection, and is suited for a
wide variety of general-purpose applications that operate off 3.3-V or 5-V input.
