The PTN78020 is a series of high-efficiency, step-down integrated switching regulators (ISRs), 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 28–V
dc power. In new designs they should be considered in place of the PT6620, PT6650, PT6680, and PT6880
series of single in-line pin (SIP) products. The PTN78020 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.
Operating from a wide-input voltage range, the PTN78020 provides high-efficiency, step-down voltage
conversion for loads of up to 6 A. The output voltage is set using a single, external resistor. The PTN78020W
may be set to any value within the range, 2.5 V to 12.6 V, and the PTN78020H from 11.85 V to 22 V. The output
voltage of the PTN78020W can be as little as 2 V lower than the input, allowing operation down to 7 V, with an
output voltage of 5 V. The output voltage of the PTN78020H can be as little as 3 V lower than the input, allowing
operation down to 15 V, with an output voltage of 12 V.
The PTN78020 has undervoltage lockout, an integral on/off inhibit, and includes an output current limit and
overtemperature protection.
