The PTN78020A is a series of high-efficiency buck-boost-integrated switching regulators (ISR), that represent the
third generation in the evolution of high-performance power modules designed for industrial use. The wide-input
voltage range makes these modules suitable for a variety of applications that operate off 12–V, 24–V, and
tightly-regulated 28–V dc power. In new designs, they should be considered in place of the PT6640 and
PT78NR100 series of single in-line pin (SIP) products. The PTN78020A is smaller and lighter than its
predecessors, and has either similar or improved electrical performance characteristics. The caseless,
double-sided package has excellent thermal characteristics, and is compatible with TI's roadmap for RoHS and
lead-free compliance.
The PTN78020A operates over an input voltage range of 9 V to 29 V, and provides high-efficiency,
positive-to-negative voltage conversion for loads of up to 4 A. The output voltage is set using a single external
resistor, and may be adjusted to any value within the range, –15 V to –3 V.
